摘要:

针对MIMO雷达的信号特点,采用了一种多角度的雷达侦察方法,从不同的方位获取同一部雷达的独立信号样本。并在此基础上,运用主分量分析方法估计信号波形个数,运用独立分量分析的盲源分离方法分离出MIMO雷达信号的各个正交分量,最终以正交频分线性调频信号为例,在信噪比为0 dB的情况下对该信号进行了仿真分析,其结果验证了该方法的有效性。

Abstract:

In view of the characteristics of the MIMO radar signal,a multiangle radar reconnaissance method is adopted in this article.By collecting independent signal samples of the same radar in different directions,Principal Component Analysis(PCA) can be used to estimate the number of signal waveform and Independent Component Analysis(ICA) can be used to isolate all quadrature components of the MIMO radar signal.Finally,in the case of SNR being 0dB,the orthogonal frequency division multiplexinglinear frequency modulation signal is taken as an example for simulation and analysis.Results show that this method is effective.

Key words: MIMO radar;reconnaissance identification;blind source separation;PCA;ICA
