Multi-target Parameter Estimation in Symmetry Triangular LFMCW Radar Based on Envelope Compensation
摘要
Abstract
Multi-target parameter estimation is a difficult problem in moving target detecting of symmetry triangular linear frequency modulation continuous wave ( STLFMCW) radar.A method for multi-target parameter estimation,which mainly uses the envelope migration,is proposed.Firstly,the motion model of multi-target is established,and the error factor which causes envelope migration is derived by analyzing the echo signal of the targets.Then,the velocity matrix,which con-tains the velocity information of targets,is obtained by pairing the peaks value of positive frequency modulation signal and negative frequency modulation signal.Furthermore,the ambiguous targets can be detected by using the velocity matrix to a-chieve the echo’ s envelope migration compensation and then re-pairing the compensated peaks.Finally,the targets accurate information is obtained by rejecting the false targets.The effectiveness of the proposed method is demonstrated by simula-tions.关键词
