"Truth is within the range of a cannon." This famous quote by Bismarck, the iron-blooded chancellor of Germany, is a household name, speaking of the law of the jungle in modern society. Only with a strong national defense force can we grasp the right to speak in the international struggle and win space for the survival and development of our own country and nation.
Since the beginning of the founding of New China, the development of poverty and whiteness has gone through countless hardships, and the same is true of the national defense industry, which has relied on the hard work of generations from scratch to have today's situation. Behind this contains the touching stories of countless military workers burning themselves and serving the motherland.
Wu Jianqi is such a selfless and dedicated scientist in the field of military industry, his name may not be known to so many people, but his achievements will always protect the motherland.
Childhood
In 1966, Wu Jianqi was born in Jiangsu, his father was a soldier, perhaps the father of the military also had high hopes for his son, so he gave him a resounding name - Jianqi. I hope that he can inherit his father's business and continue to devote himself to the military to defend his family and the country.
When he was four years old, his father's work was transferred, and Wu Jianqi followed his father to Luzhou, Sichuan, where he began his childhood life.
Since he was a child, he has shown an extremely strong curiosity and far beyond the learning ability of ordinary people, because the material conditions of that year were limited, Wu Jianqi made toys by himself, not only can play by himself, but also give toys to other children to play together, no matter what material, as long as it is sent to his hand, he can play a new trick.
At the age of school, Wu Jianqi entered the school, he was simply very happy, the thirst for knowledge is his innate quality, there are many smart students, there are many students who are willing to work hard, but there are often very few students who have both, Wu Jianqi is one of them, and the teachers of the school praise him.
Not only that, he is also very humble, good at following the advice of others, can clearly understand his own position, with the help of teachers and classmates, his results in each subject are very good, even sports have not fallen behind, before the college entrance examination, even have the opportunity to become a professional athlete with the identity of sports students.
But he already had a plan in mind, and he wanted to defend his country with the scientific knowledge he had learned, just as his father defended his country with a steel gun in his hand.
Go out and study
In 1983, Wu Jianqi was admitted to Beijing University of Aeronautics and Astronautics with excellent results, and in terms of professional choice, he chose the radio engineering most relevant to national defense science and technology, and became a student in the Department of Radio Engineering of Beihang Airlines.
In the days of studying at Beihang Airlines, Wu Jianqi devoted himself to the study of knowledge by virtue of the spirit of not being afraid of difficulties and not being afraid of hardships that he had cultivated in the military family since he was a child.
After completing his undergraduate studies, in 1987, Wu Jianqi entered the University of Electronic Science and Technology of China to pursue a master's degree, where he further learned the knowledge of the radio field, laying a solid foundation for him to become an expert in the field of radar in the future.
After graduating with a master's degree in 1990, Wu Jianqi, who was full of interest in scientific research, chose to work at the Research Institute of China Electronics Technology Group, and in this year, another major event occurred in the world, the Gulf War broke out.
This was the first modern war in the true sense after the end of World War II, and the US military exerted its combat effectiveness that shocked the world with its high-end weapons and equipment. Since then, the war has been more than a contest of willpower and numbers, the development of science and technology has made it completely impossible to fight across generations of weapons and equipment, and the most eye-catching thing in this war is the STEALTH FIGHTER OF THE US MILITARY.
The U.S. stealth fighter F117 carried out a precise strike at Iraq's important military facilities, while Iraq's anti-aircraft fire was powerless to fight back, because the radar equipped by Iraq at that time could not detect such advanced stealth aircraft. Therefore, the air supremacy was completely lost, and they could only be beaten by the US military on the ground, helpless.
The strength of the stealth fighter has shocked the domestic military and scientific and technological circles, and everyone knows that if we cannot develop effective countermeasures, in the face of the US military's stealth aircraft, our airspace will be in danger, and the enemy aircraft will enter no man's land, posing a huge threat to the mainland's homeland security. The relevant scientific research department immediately recognizes the seriousness of the problem, and the relevant research must be carried out immediately.
The road to scientific research
The reason why the stealth aircraft is a huge threat is because ordinary radar can not detect its existence at all, at that time China's level of science and technology is still a big gap from the United States, and the level of science and technology directly affects the military level, in order to ensure national security, the mainland's radar detection level must be greatly improved.
Wu Jianqi looked in his eyes and was anxious in his heart. After graduating with a master's degree, he was engaged in radar-related research at China Electronics Technology Group, and how to develop a radar that could detect stealth aircraft became his life goal.
Before starting the relevant work, Wu Jianqi said the bold words of "turning American aircraft into scrap copper and rotten iron", determined to make American aircraft have nowhere to hide, and he was determined to devote himself to the front line of "anti-stealth" and become an "anti-stealth" fighter.
To be "anti-stealth", you must first figure out how the plane is invisible. Aircraft were used in warfare as early as the First World War, and the biggest natural enemies of this expensive weapon were anti-aircraft guns on the ground and various missiles that have evolved with each passing day since the invention of radar.
Radar is like a pair of eyes, and the plane that is stared at by these eyes becomes a living target, and it is basically impossible to escape the fate of being hit by a missile. In order to improve the survival rate of the fighter, the development of stealth fighters began to be put on the agenda, and the contest between spear and shield began.
Stealth aircraft are not really invisible, but through special paint materials and aircraft structures that make it impossible for radar to detect. As we all know, the working principle of radar is to determine the exact position of the aircraft by emitting radar waves, analyzing the radar waves reflected back after encountering obstacles.
If the reflective surface of the aircraft is small enough to reduce the amount of reflection of radar waves, then the results of the radar analysis are no longer accurate, and the aircraft has achieved the goal of stealth.
This theory was first produced in the Soviet Union, but it was eventually put into practice by the Americans, and the shooting down of a large number of American warplanes equipped by Israel in the Fourth Middle East War strengthened the Determination of the Americans to develop stealth aircraft. In 1982, the F117 was officially delivered to the U.S. Air Force, and there was a scene in the Gulf War mentioned above.
At that time, the main research direction of radar was microwave radar, which was developed on the basis of meter-wave radar, so two camps were formed in the research direction of solving the problem of anti-stealth.
One faction advocated continuing research on existing microwave radars to improve accuracy so that they could find objects with smaller reflective surfaces, which was also the idea of most people at that time, after all, research on top of advanced results could become more advanced.
But Wu Jianqi no longer thinks so, and with years of study and research in the field of radio, he is keenly aware that the meter-wave radar may have an advantage in the field of exploring stealth fighters.
This view of his has been questioned and opposed by many people in the industry, who believe that the research on this backward technology is a complete waste of national resources, and this deviation cannot occur in this key research field. But Wu Jianqi firmed up his idea and set the research direction on the mipo radar.
In 1992, Wu Jianqi's application for the topic of mipo radar was finally supported, and his research work began, and he knew in his heart that it was impossible to follow the old path of other countries, and only by creating a new road could he realize his pride and ambition.
At that time, Wu Jianqi did not expect that this road would take twenty years.
With no experience to learn from, and no mature model to refer to, Wu Jianqi and his team started from scratch. Starting from the most basic theory, in the era when computers are still luxury, overcome difficulties to build models and transform the theory into practice step by step.
He spent years to find the relationship between the stealth conditions of the stealth aircraft and the wavelength of the radar, proving that the meter-wave radar was easier to detect the stealth plane, and became a key to opening the door to anti-stealth.
In 1999, American stealth bombers bombed the mainland's embassy in the Federal Republic of Yugoslavia, resulting in the death of three mainland personnel, and the news spread back to China, causing a national uproar and anger among the people. Embassies abroad are an extension of territory, and this kind of behavior of the United States is tantamount to naked provocation, relying on its advanced scientific and technological strength and having no fear.
This news also stimulated Wu Jianqi and his team members, at this time their scientific research is in a critical period, Wu Jianqi since leading the team to tackle the topic, the responsibility on his shoulders is also getting heavier, in the face of such a situation, he gave full play to the leading role of a Communist Party member, always the first overtime work on holidays, leading the team to overcome one difficulty after another.
In 2000, Wu Jianqi and his colleagues finally completed the presets of all the subjects, unveiled the mystery of stealth aircraft, and left their own strong mark in the history of radar development.
Despite such important progress, the follow-up work was still very complicated, and Wu Jianqi did not have time to celebrate, so he threw himself into the design and finalization of the radar.
In the blink of an eye, another decade, in 2012, the anti-stealth mipo radar designed by Wu Jianqi finally completed the first-level design finalization work.
Wu Jianqi studied hard for twenty years and finally reaped the fruits, and the hardships and hardships in it were known only to him. What he always shows to those around him is an image of an intellectual who is calm and calm, and has a gentle tone. The sword blade came out of the grinding, and the plum blossom fragrance came from the bitter cold.
With his own practical actions, he fulfilled his vow to turn The Us stealth plane into a scrap of copper and iron. The technology of meter wave radar detection of stealth aircraft was applied to air combat. Since then, there have been countless pairs of "eyes" on the mainland's airspace that have seen everything, and the US stealth plane has no longer had no fear.
This remarkable achievement has shocked the whole world, and in this era when science and technology is the first productive force, having such advanced technology will undoubtedly make our country's national defense cause go to a higher level.
Along the way, Wu Jianqi did not forget his original intention, with his contributions in the field of national defense, he has won various awards many times, including 1 first prize and 3 second prizes of national scientific and technological progress, and many first and second class science and technology awards for national defense.
The mibo three-coordinate radar and the mibo sparse array four-coordinate radar he presided over are the first in the world, so that the mainland's radar technology has entered the world's leading ranks.
Because of this, Wu Jianqi has also become a "national treasure" scientist in people's hearts. On the road of development of the mainland over the past seventy years or so, whether it is national defense science and technology or agricultural production, from aircraft rockets to small screws, behind the achievement of every achievement, there are countless people like Wu Jianqi who are silently paying.
Today, Wu Jianqi is not lying on the merit book to stop moving forward, the battlefield of scientists is in the laboratory, and he is now the chief scientist of China Electronics Technology Group Corporation, still fighting in the front line of national defense science and technology work.
People like him who have devoted their efforts and energy to the cause of the motherland are the people who are truly worthy of learning from the younger generation. Only in this way can our country prosper step by step.
