Abstract

In BiSAR (Bistatic SAR), scattering characteristic of target varies with the geometric configuration of transmitter and receiver. Single angle SAR image can only provide limited information of a target, which hinders the recognition of targets and limits the application of BiSAR images. To overcome this shortage, a multi-angle fusion method is proposed. Sixteen SS-BiSAR (Space-Surface BiSAR) images using Compass-2/Beidou-2 as opportunity illuminator in different azimuth and elevation angles are obtained via Back-Projection algorithm. Then a fusion image is gained through non-coherent superposition. The result of fusion image shows that: multi-angle fusion is able to capture specular reflection of targets. Structure characteristics of targets are observed in fusion image while in single angle image only a part of target structure is visible. By multi-angle fusion, a continuous outline of target is achieved, which is very advantageous to interpretation of BiSAR images.
