Abstract :

Artificial Aperture Radar (SAR) is a remote sensing system used to capture high-resolution images. This radar is installed on a platform (aircraft or satellite). Ideally, the platform is assumed to be moving at a constant speed along a straight path, while atmospheric disturbances and aircraft maneuvers, and other factors cause the platform to change in direct velocity and deviate from the nominal path, and a fuzzy error occurs in the received echo. As a result, there will be distortions in the final image. In this article, we will analyze the effects of platform motion on the artificial aperture radar image and the need to compensate for motion errors.
