Abstract:

The traditional FMCW (frequency modulation continuous wave) radar has its own defect of range-velocity coupling in multi-target detection.In this paper an improved method by using FMCW+CW is presented.Using the speed estimated by the Doppler frequency of CW echo to eliminate the false target of radar target detection,it can identify the true targets from the multi-objective effectively,and estimate the speed and distance information of the target,Computer simulation shows that the analysis is correct and the method is practical.
