Abstract
Multi-path effects on target detection are analyzed in order to improve target detection performance of Linear Frequency Modulation Continuous Wave(LFMCW) radar under complex environment. A model is proposed based on Time Reversal(TR) technology considering its advantages and the effectiveness of the model is discussed. The detection performances of different methods are compared through the simulation. Simulation results verify that the proposed method outperforms other traditional methods on target detection.
