Abstract

Synthetic Aperture Radar (SAR) imaging algorithm for the moving targets with some motion irregularities are investigated. For accurate SAR imaging of the moving targets, position and the velocity of the object according to the radar platform must be known accurately. To calculate the instantaneous range and velocity of the object, local radar platform with one transmitter-two receiver (OT-TR) is considered. After the range-bin alignment of the returned signal in each receiver, target's angular position and velocity can be determined by using the phase difference of the receivers. Motion effect free SAR images of moving targets can only be achieved by doing the phase compensation which uses the target's location, direction and speed along the aperture. In this paper, the formulation for rejection of motion irregularities in SAR images is presented and some computer simulations are given.
