Abstract

In recent years, the imaging theory and technology of missile-borne synthetic aperture radar (SAR) has become one of the important research topics. The missile-borne platform usually requires high-precision imaging from the front and side view, and the missile is affected by the airflow, and the flight trajectory changes greatly and randomly during the air flight. For this reason, a motion compensation algorithm is required. At the same time, due to the real-time and large computational requirements of missile-borne SAR imaging, it is of great significance to use a higher-performance graphics processing unit (GPU) platform for SAR time-domain imaging processing. This paper introduces the use of GPU to implement extended Wavenumber-domain (EOK) algorithm and large-squint motion compensation algorithms.
