Comparison of medium resolution algorithms for spacecraft on-board SAR image generation

Traditionally, spacecraft synthetic aperture radar (SAR) processing has been performed on the ground. This is mainly due to the huge amount of computation, high reliability and resources that SAR processors require. However, new space-qualified technology will offer an adequate scenario for producing medium resolution SAR images. In this framework, this paper presents a comparative study among the most appropriate algorithms for on-board implementation. A feasibility assessment and a quality analysis of the identified processors for on-board SAR medium resolution imagery are provided.
