Traditional radio spectrum monitoring lacks effective monitoring on the mixed signals overlapped in the same frequency bands spectrum.In the circumstance that the source signal and the propagating channel are unknown,the blind source separation could separate mixed signals and obtain pure source signal,so is an effective method for monitoring this mixed signals.Thus the blind source separation is applied to spectrum management monitoring.This paper describes the concept of blind source separation,and analyzes the algorithm of blind source separation for short wave spectrum management monitoring.The application of this technology in the electromagnetic spectrum management monitoring is simulated,thus providing certain technical support for spectrum management monitoring.
