Estimation of Phase, Range, Doppler of Targets Using Maximum Likelihood Estimator

摘要

This paper presents maximum likelihood estimators (MLE) for radar signal processor which can estimate range, Doppler and phase of received signal. Scanning radar collects pulses which are processed. Two approaches are discussed. In first approach, parameters of each pulse are estimated and then average of all pulses is calculated. In the second approach, all pulses are added and then maximum likelihood estimation is performed. The simulation results show that the estimators accurately estimate the signal parameters.
