反辐射导弹检测算法研究

反辐射导弹(ARM)是现代战争中的一种“硬杀伤”武器,对防空雷达系统构成了严重的威胁。本文针对目前我国防空雷达现状,对反辐射导弹发射告警的检测识别算法作了研究。根据雷达回波的特点,为有效抑制强载机信号提出了功率函数的概念,用来作为对ARM加速度估计的标准。最后得出了基于脉冲相关技术的ARM检测和识别算法,并对该方法的检测性能进行了分析。

Study on Detection and Identifying Algorithm of ARM

Anti-radiation missile (ARM) is a kind of "hard killing" weapon in the modern war, and it poses a serious threat to the anti-air radar system. In view of the actualities of anti-aircraft radars in our country, the paper deals with an algorithmic study of detection and identification for early warning of ARM launching. At the beginning, the paper proceeds from how to restrain aircraft signal effectively on the base of the characteristic of radar echo, and further it puts forward a concept of power function, so that to make it as a standard for both detection and identification as well as estimating the acceleration of ARM. At last, it attains the method of algorithm on detecting and identifying ARM based on the pulse correlation technology, and gets an analysis for the detection performance of the method.
