摘　　要：频率捷变雷达发射的信号具有相邻发射脉冲的载频是随机跳变的特点,在面对间歇采样转发干扰时会出现无法区分真实与假目标的情况。针对上述问题,提出基于长短记忆(LSTM)神经网络搭建分类模型,实现对干扰的识别并进行抑制。最后采用压缩感知算法对目标回波进行重构。仿真实验验证了该方法的有效性。The signal transmitted by frequency agile radar has the characteristics that the carrier frequencies of adjacent transmitting pulses hop randomly.In the face of intermittent sampling repeater jamming,it is possible that the radar cannot distinguish between real targets and false targets.In view of the above problems,this paper builds a classification model based on long short term memory(LSTM)neural network to realize the recognition and suppression of jamming.Finally,the compressed sensing algorithm is used to reconstruct the target echo.The simulation experiment verifies the effectiveness of this method.
