A direct-path-wave purified approach to passive radar based on blind source separation
Qiurui He · Ship Science and Technology · 2013
To the problems the direct-path-wave is interfered by multi-path interference signals and noise in the reference channel of the passive radar,a method based on blind source separation with global optimal algorithm was proposed which can restrain disturbance,it achieve the direct-path-wave purified in the reference channel.And on the basis of the autocorrelation function waveform and doppler sensitivity,analysising the effection of the detection performance by the direct-path-wave purity.The simulation results show that the method can get the high purity of the direct-path-wave,compare with the not purification detection system,the detection performance shows significant improvement,and the method is simple to operate,and easy to achieve.
