战场侦察雷达对炸点目标的识别方法

在战场侦察雷达的应用中,对炸点目标的探测和识别,一直是一个重要课题。针对炸点和普通目标的回波特性作了讨论。文中研究了炸点和普通目标回波信号经动目标检测(MTD)处理后的特征,发现了两种目标特征谱在多普勒滤波器通道响应的特点,提出了一种在多普勒滤波器通道进行二元积累,设定检测门限来判定炸点目标的方法;另外,对目标多普勒响应的滤波器分布特征作了分析,利用炸点目标与普通目标的多普勒分布差的区别进行目标识别,并取得了很好的效果。

Classification Method of Howitzer Impact Point for a Battlefield Surveillance Radar

In the application of the battlefield surveillance radar,the howitzer impact point detection and identification are important.In this paper,the echo characteristics of a howitzer impact point and a normal target are discussed.Through the investigation of the echo signal after MTD,we find the difference between a howitzer impact point signal and a normal target signal,thus a method to identify howitzer impact point from other battlefield targets is introduced,which includes binary integration on Doppler filters.The analysis of echo signal Doppler distribution is made,based on which we propose an identification method using Doppler distribution and get a good result.
