岸防相控阵雷达信号处理机工程实现中的几个问题

从工程实现角度出发,探讨了岸防相控阵雷达信号处理机的几个实际问题.由于波束内发射脉冲数较少,跟踪时波束又可能采取跳跃式扫描,因而在实现固定目标对消、自适应滤波、低速目标检测时有效数据率会降低.本文介绍了采取杂波存储方式弥补脉冲数不足的方案,并讨论了实现中的问题.

Several Problems in Engineering Implementation on Signal Processing System of Coast Defense Phased Array Radar

From the point of view of engineering implementation, several practical problems in the design for signal processing system of coast defense phased array radar are discussed. The effective rate will decrease while realizing stationary target cancellation, adaptive filtering and slowly moving target detection because there are fewer pulses transmitted in a beam and the beam may scan in hopping mode while tracking. To make up for the deficience of pulses, a method to use clutter maps is presented and some problems in implementation are discussed.
