摘要
目的为现役某分辨搜索雷达研制一种新的目标自动检测系统．方法采用ＤＳＰ和其他高速芯片组成一种现代数字信号处理硬件平台，充分利用雷达回波的幅度信息，用能量加权法精确计算目标中心．结果有效地抑制了目标分裂和边缘效应，计算角分辨率为０．０４°，距离分辨率为３０ｍ，处理能力高达３０００批次／Ｔ，其处理速率为原系统的１０倍．结论该系统满足了高分辨搜索雷达实时。
Aim To study and develop an automatic detection system for one high resolution searching radar in active service. Methods A new structure of modern digital signal processing hardware platform with the combination of DSP and other high speed chips was adopted in the system. The information in the radar echo was fully used, and an energy weighting method was employed to precisely locate the targets. Results This system efficiently suppressed the split of target and edge effect. The computed resolution of azimuth was 0 04° and the resolution of distance 30 m. Up to 3 000 targets could be detected within a scan cycle, its processing rate was 10 times high compared with the old system. Conclusion This system meets the requirements of high resolution searching radar to precisely detect multi batch targets in real time.
