A Solution for Bistatic Motion Compensation

Abstract

Bistatic synthetic aperture radar (SAR) missions have become attractive in the last years, because of their higher degree of freedom in choosing transmitter and (passive) receiver motion trajectories. In order to take advantage of this increased imaging flexibility, adequate processing algorithms have to be developed, implemented and verified with experimental data. Currently some promising approaches have been published in this area. A further step in improving the focusing results within a bistatic SAR constellation where transmitter and receiver are mounted on different platforms essentially comprises the bistatic motion compensation (MC). We present a geometrical MC approach which requires high accurate position and velocity information of transmitter and receiver.
