舰载雷达中舰速补偿研究

舰载雷达由于舰船的运动,其动目标检测系统必须进行补偿。本文结合某单脉冲舰载跟踪雷达信号处理机的研制,提出了舰速补偿的2种方法。第1种方法采用改变MTI滤波器的凹口实现,第2种方法通过对回波信号进行谱搬移之后对目标速度进行补偿实现。通过分析与比较,虽然2种方法都能取得好的效果,但第2种方法的运算量明显小于第1种。该方法已成功用于某雷达信号处理系统。文中给出了该雷达信号处理系统的基本组成并详细论述了该方法的具体实现过程。

Study of compensation of ship speed in ship-borne radar

In ship-borne radar,the MTD processing system must be compensated because of the movement of the ship.Two algorithms are studied in one ship-borne monopulse tracking radar signal processor.One is to change the notch of the MTI filter,the other is to transfer the spectrum of the echo and then to compensate the velocity of the target.Both the algorithms can get a good result.But through analysis and comparison,the second algorithm takes less operation and this algorithm is used in the signal processing system...
