Modular design of SAR electronics

To achieve a better balance between investment and return, the development of more generally applicable technologies (generic, modular, multi-functional) or the application of the proven off-the-shelf technologies are the key issues. Besides cost effective design and manufacturing, the competitiveness can be significantly improved with a wider applicability of the technology. This paper discusses the modular design approach and the implementation related aspects of a multi-frequency, multi-mode, high-resolution SAR system.
