Modular design of SAR electronics

To achieve better balance between investment and return, the development of more generally applicable technologies (generic, modular, multifunctional) 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 multifrequency multimode high-resolution synthetic-aperture-radar system.
