Abstract :
In this paper, the motion compensation of inverse synthetic aperture radar (ISAR) is carried out in the two dimensional frequency domain. It is able to eliminate the extra processing in range and becomes very promising in real time radar imaging. Two new criteria, i.e. grayscale peak minimum and average burst derivative minimum, are presented. Computer simulation of ISAR motion compensation based on the real data of reduced-size metal model B-52 collected in a microwave anechoic chamber, is carried out. The reconstructed images show that the two proposed criteria are feasible. The two-dimensional search is conducted to investigate the global properties of the two proposed criteria
