Xi'an, November 5 (China News Network) Reporter Alina learned from the Shaanxi Provincial Institute of Cultural Relics Protection on the 5th that the Shaanxi Provincial Institute of Cultural Relics Protection, together with Xi'an Technological University and the Qin Shi Huang Emperor Mausoleum Museum, recently carried out phased summary and on-site tests of the first application of phased array radar in the security of Shaanxi field cultural relics in Qinling Lishan Park, and the project team carried out on-site tests and feasibility verification in Lishan Garden and Terracotta Warriors No. 1 Site Pit respectively.
Since 2021, the project team researchers have conducted detailed investigations on 8 large-scale open-air monument site areas in Xi'an, Weinan, Xianyang and other places to understand the distribution characteristics of field cultural relics and the current security status, and further clarify the feasibility of the application of phased array radar system in field cultural relics security. At the same time, the platform system software research and development and evaluation are completed, and the functions of radar data access, radar real-time monitoring, target trajectory playback, target hierarchical early warning and photoelectric linkage after early warning are realized.
In order to further strengthen the preventive protection of field cultural relics in Shaanxi Province and actively introduce cutting-edge cutting-edge science and technology for the protection of traditional culture and precious cultural relics, the Shaanxi Provincial Institute of Cultural Relics Protection took the lead in organizing the application of the "Research on the Application of Phased Array Radar for the Preventive Protection of Immovable Cultural Relics in the Security of Field Cultural Relics" project approval report to the Shaanxi Provincial Cultural Relics Bureau in 2019, and the Shaanxi Provincial Cultural Relics Bureau approved the project in 2020. The project is scheduled to be completed in 3 years and has now entered the field trial phase.
As a large province of cultural relics, Shaanxi has a large number of historical relics and cultural relics, of which the scattered and poor protection conditions of the field cultural relics a large number of, especially the imperial tombs and other large sites, large area, high grade, has become the highlight of Shaanxi's cultural relics resources and the focus and difficulty of safety protection. The introduction of high-tech phased array radar for the first time in the Shaanxi field cultural relics security application and test, will completely change the field cultural relics civil air defense, material defense, technical defense and other traditional methods, this move in Shaanxi field cultural relics safety and security work is of landmark significance.
Phased array radar is a phase control electronic scanning array radar, the use of a large number of individually controlled small antenna units arranged into an antenna array, each antenna unit is controlled by an independent phase shift switch, by controlling the phase emitted by each antenna unit, you can synthesize different phase beams. Phased array radar fundamentally solves the inherent deficiencies of traditional mechanical scanning radar, and its reaction speed, target update rate, multi-target tracking capability, resolution, versatility, and electronic countermeasure capabilities are far superior to traditional radar.
