Blind Source Separation Method for MIMO Radar Signal
Jia Fang · Electronic Science and Technology · 2015
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 0d B,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.
