To weaken the strong noise in passive detection system,multi-reference adaptive noise cancellation algorithm.By using the transmission channel diversity between target echo signal and noise,multi-reference signals are obtained through minus between the received signals of every receiving element.Simulation result shows that this algorithm can offset noise effectively,so that the weak signal detection performance is improved.
