NO.1 Technological breakthrough
01 Array Integrated Technology
At present, virtual channel technology generally has the problem of high false alarm, and the blur problem caused by the extreme sparseness of the array is highlighted in order to increase the aperture, which greatly reduces the credibility of the data.
An Zhijie adopts advanced intelligent array comprehensive algorithm, using the supercomputing server to comprehensively iterate more than 1,000 times, and the core index SLL reaches -30 ~ -45dB, far exceeding the ULA theoretical limit, achieving higher dynamic range, greatly reducing virtual alarm and solving the problem of weak target flooding.
02 Constant false alarm technology
The traditional CA and OS constant virtual alarm algorithms have been unable to meet the detection of dense targets and clutter background, An Zhijie adopts the self-defined adaptive constant false alarm detection algorithm, which greatly improves the detection ability of dense targets and effectively suppresses the edge effect of clutter.
03 Super resolution technology
Aperture by the radar size constraints resulting in beam width is not narrow enough, the use of super-resolution technology to further improve the aperture to achieve higher angle resolution, An Zhijie using the spatial spectrum estimation of the strongest resistance to multipath ability of the subspace fitting algorithm, effectively improve the 4 to 6 times angle resolution capability, supplemented by advanced source number estimation algorithm, so that the ability of DOA greatly improved.
04 Target tracking technology
Traditional tracking technology has the contradiction of target and resolution ability, target loss, trajectory instability and fracture, etc., and is limited by the computing and storage resources of traditional chips, combined with the complexity of the automobile scene, the overall level of tracking is limited. Combining the maneuverability characteristics of the vehicle and the undulating effect of the radar, An Zhijie adopts advanced IMM-JIPDA and UKF technology to take the traditional tracking technology to a new height.
05AI technology
An Zhijie's deep learning network customization capabilities accumulated over the years, coupled with a complete data iteration toolchain, implanted cnN and Transformer, have greatly improved the ability of target recognition and scene segmentation.
