摘要
本文提出一种基于自适应线性预测滤波器技术实现的反辐射导弹 (ARM)检测新方法 ,可以有效地将雷达回波中的强载机信号消除而保留微弱的ARM信号 ,使ARM的检测更加迅速、可靠 .仿真结果表明 ,这种方法可以在低达 - 2 0dB的ARM与载机回波功率比中实现ARM信号的有效检测识别 。
A new method for ARM detection based on Adaptive Linear Prediction Error Filter (ALPEF) is proposed in this paper. The method is proved to be fast, reliable for detecting ARM signal in a very low aircraft to ARM signal ratio. Its mechanism is based on the elimination the strong aircraft signal from the radar echoes. Computer simulation results show that a very good detection performance is achieved in a -20 dB aircraft to ARM signal ratio, so that a reliable early warning of ARM launching can be given.
