摘要
随着汽车雷达的广泛应用,雷达之间的相互干扰越来越受到人们的关注。为了缓解雷达相互干扰的问题,本文提出了一种基于迭代阈值检测和LSTM的干扰抑制方法,首先迭代检测干扰信号的位置,然后利用LSTM恢复出被干扰的回波信号。经过仿真验证,所提方法能有效抑制LFMCW雷达的相互干扰,经过处理后雷达能准确获取目标信息。
With the wide application of automotive radar,mutual interference between radar is getting more and more attention.In order to mitigate radar mutual interference,this paper proposes an interference suppression method based on iterative threshold detection and LSTM.Firstly,the position of the interference signal is iteratively detected.Secondly,the interfered echo signal is recovered using LSTM.The simulation results show that the proposed method can effectively suppress mutual interference between LFMCW radar,and the radar can accurately acquire target information after interference suppression.
