机载相控阵雷达降维STAP信号处理机的设计

由于巨大的运算量和其他技术问题的存在，空时二维联合处理（STAP）技术的实现必须进行降维处理。文中设计了一种先时后空白适应级联降维处理信号处理机。该信号处理机主要由预处理、通道处理、STAP波束形成和多CPU等模块组成，主要完成通道校正与均衡、动目标显示、数字脉冲压缩和多普勒滤波、STAP波束形成和恒虚警率检测，以及解模糊的功能。

A Design of Dimension-reduced STAP Signal Processor in Airborne Phased Array Radar

Because of huge operations and other technical problems, dimension-reduced processing is the necessary of the implement of STAP technique. This paper designs an adaptive dimension-reduced signal processor in which the temporal domain process is first and the spatial domain process is later. This signal processor is constitutive of a serial of blocks, as the preprocess block, the channel process block, the STAP beam forming block and the multi-CPU block, etc. It mostly implements some functions, such as adjusting and equipoise, moving target indicator, digital pulse compression, Doppler filter, STAP beam former and constant false alarm rate detection, and solution of ambiguity.
