摘要
研究机载火控雷达检测地面慢速目标的方法。由于机载火控雷达采用前向阵,脉冲重复频率低,使得杂波多普勒频率多重模糊。分析了机载火控雷达检测地面慢速目标的特点,提出了一种非自适应的干涉对消法与自适应的AMTI方法相结合的检测方法。分析结果表明,这种方法对雷达平台运动参数的估计精度要求较低,工程上易于实现。
In this paper, the algorithm for airborne fire - control radar to detect slowly moving ground targets is discussed. The systcm of this kind is characterized by its forward looking antenna and low PRF, which results in thc highly ambiguous Doppler frequency of ground clutter. The features of detection of slowly moving ground targets by means of the airborne fire - control radar are analyzed, and a moving targets detection algorithm combining unadaptive interferometer cancellation algorithm with adaptive moving target indication is presented. The results show that the method can work well with the condition that the estimation accuracy of the radar carrier moving parameters is lower,and is feasiblc in the engineering.
