A radar target recognition method based on backward cloud model is proposed in this paper.Firstly the certainty degree of cloud drop is established based on the mode-1 criteria,and then the normal backward cloud model is established for the high-resolution range profile(HRRP) unit.Meanwhile,the backward cloud membership is defined to characterize the probability of the test sample belonging to a training class.Simulation results based on the HRRP dataset of five aircraft models demonstrate that the proposed...
