Maneuvering SAR Imaging Algorithms

Traditional imaging algorithms of uniform motion SAR are not suitable for maneuvering imaging. Time-domain algorithm is too computational to be suitable for realtime imaging. Frequency domain algorithm mainly relies on the solution of two-dimensional spectrum. It is usually suitable for SAR imaging in a single motion mode, and its applicability is poor. A maneuvering SAR imaging algorithm based on the separation of azimuthal motion information is proposed. The algorithm breakes through the limitation that the traditional frequency domain imaging algorithm can only be applied to a single motion state. Through simulation, the applicability of the algorithm in the traditional uniform motion, three-dimensional uniform motion, three-dimensional uniform acceleration motion and other motion states is verified. The algorithm is simple, stable and applicable.
