摘要
提出一种基于自适应线性滤波和分段解线调法的反辐射导弹(ARM)检测技术。先利用线性预测滤波器抑制掉强载机信号,然后利用分段解线调法估计ARM信号的调频斜率参数和起始频率参数。仿真结果表明,该方法能够将微弱的ARM信号准确的检测出来,从而实现实时告警。
A new method for ARM detection Based on adaptive linear prediction error filter and subsection deehirp is proposed. Firstly, the aircraft signal is restrained with adaptive linear prediction error filter, then the parameters of FM slope and those of origination slope of ARM are estimated via subsection dechirp. The simulation results show that an accurate detection of weak ARM signal can be achieved, so that a reliable early warning can be given.
