Several New Methods for the Extraction of Time-Domain Scatterring Signal Based on BP Neural Net

Zhang Liangjie(Dept.of Automation,Tsinghua Univ.,Beijing l00084)Wang Wenbing(Dept.of Information & Control Engineering,Xi'an Jiaotong Univ.,Xi'an 7l0049)  
In this paper, the DRS(directly receiving signal) feature detection method and the "interrupted" adaptive DRS cancellation method for time-domain scattering signal extraction based on BP neural network are presented. In the meantime, the DRS cancellation method which has been preprocessed with decorrelation technique and the adaptive processing method of the directly subtracted signal are also introduced. Some computer simulations have shown the effectiveness of those algorithms.
