Based on the mining analysis of the cluster structure of the long-range portrait of 3D-object, a physically based mathematical model of the temporal profile of the pulsed radar cross section of the object in the form of a finite mixture of standard pulses is proposed. The methodology and results of identifying model parameters using a modified EM-algorithm are presented.
