随机共振在方位估计中的应用
Application of stochastic resonance in detection estimation of signals
摘要
Abstract
Under low signal-to-noise condition,the weak signal estimation will deviate.In order to estimate accurately,stochastic resonance is used in the algorithm of direction estimation.The signal is obtained after stochastic resonance whose signalto-noise is enhanced.The algorithm of direction estimation is used to estimate the direction.CBF,MVDR and MUSIC is used in simulation research with the weak sine wave and BPSK.The experiment results show that applying stochastic resonance to directe estimation conforms to the theoretical analysis and the accuracy of the direction estimation of targas is increased.关键词
