总结了炮位侦校雷达常用的杂波抑制方法,如杂波图、恒虚警率等,并提出了通过航迹背景图(TBM)和径向速度精确估计来抑制杂波的新方法,分析结果表明:新方法能有效传统方法难以抑制的民航、无人机等虚假航迹目标,改善雷达在复杂环境下的目标捕获和跟踪能力。

Artillery locating & calibration radars must have great abilities in high-maneuvering and all-weather working. High multitarget capability should be provided by modern artillery locating radar in complex battle circumstance, simultaneously, the probability of false targets should be reduced, so good capability of clutter suppression is very important to artillery locating radar. This article summarizes some customary methods of clutter suppression like cutter map and CFAR, and puts forward two new clutter suppression methods including track background map and velocity accurate estimation. The practical example indicates that new methods can effectively suppress false tracks like civil aircrafts and improve the capabilities of radar in targets capturing and tracking in complex environment.
