- W3193375879 abstract "This article presents a discussion of one of the important areas of application of synthetic aperture radars (SAR) – the moving target indication (MTI) mode. The principle of trajectory signal processing in MTI systems is based on the estimation of the Doppler frequency or phase shift of the echo signals due to the movement of objects. The paper describes an algorithm for estimating the tangential velocity of moving targets for the MTI system based on the use two apertures displaced along trajectory of SAR spacecraft. The structure of the MTI system based on the analysis of phase and amplitude radar images is considered. Further, the amplitude and phase characteristics of the moving target are obtained. The block diagram of the tangential velocity estimation algorithm is given. Simulation has been performed and the features of the operation of this algorithm are presented. The errors in estimating of the target tangential velocity are determined." @default.
