| Abstract: | The mathematic model standing for undersampled and nonuniformly sampled signals of MPCSAR is developed and the corresponding imaging result representatives are also deduced in this paper.The reasons of the paired false target echoes are analyzed and the paired echoes are divided into two types,one is called "undersampled type" and anather,"velocity mismatched type".The formulas are given to locate the paired echoes and to calculate the intensity of echoes and the simulation results performed in the paper have proved the validity of those formulas. |
