INVESTIGATION OF AN ALGORITHM FOR ES TIMATINGTHE TANGENTIAL VELOCITY OF AN OBJECT FOR SPACE SAR
The article presents a discussion of one of the important areas ofapplication of synthetic aperture radars (SAR) - the moving target indication (MTI) mode. The paperdescribes an algorithm for estimating the tangential velocity of moving targets for the MTI system basedon the use two apertures displaced along trajectory of SAR spacecraft. The amplitude and phasecharacteristics of the moving point target are considered. The block diagram of the tangential velocityestimation algorithm using weight processing is given. Simulation has been performed and t he featuresof the operation of this algorithm are presented. The errors in est i mat i ng of the target tangent i al velocityare determined.
