摘要

摘要: 针对多基地雷达系统中多普勒频差导致干扰信号的去相关的问题，该文提出一种基于距离-多普勒补偿的多基雷达协同抗主瓣压制干扰方法。首先，通过不同雷达平台接收到的干扰信号的互相关函数，分析了多普勒频差对多平台干扰信号的相关性影响。其次，通过最大化时间-多普勒2维相关函数对传播延时差与多普勒频差进行估计和补偿，实现主瓣干扰抑制。然后，为了降低运算量，先利用幅度相关估计出传播延时差，再估计出多普勒频差。仿真结果表明，通过多普勒频率补偿后进行干扰信号级相消处理，可有效抑制主瓣压制干扰。

Abstract: To solve the de-correlation problem due to Doppler frequency bias for multistatic radar system, a main-lobe jamming suppression algorithm for multistatic radar based on range-Doppler bias offsetting is proposed. First, based on the cross correlation function of jamming signals of different radars, the effect of Doppler frequency bias on the cross correlation function is analyzed. Then, the time delay and Doppler frequency bias can be estimated and offset by maximizing the two dimensional correlation function of time and frequency, in order to suppress the jamming. What’s more, to reduce the amount of calculation, the time delay can be obtained firstly by cross correlation function of signal amplitude before estimating the Doppler frequency bias. Simulation results illustrate that the jamming can be suppressed effectively after offsetting the Doppler frequency bias and signal cancellation processing.
