Abstract: A method for the detection and motion parameters estimation of the high speed multi-target in narrowband radar systems is presented.The echo is separated by using the Dechirping and filtering,then the echo matrix of each target is constructed.Then a coherent phase compensation function is constructed and is compensated for each target,so that the energy of the target can be accumulated coherently,and it is helpful for target detection.With the estimated Doppler information the motion parameters can be obtained.Simulation results show that the proposed method is effective.
