摘要

This paper describes the next generation synthetic aperture radar (SAR) that enables future low cost space-borne radard missions. In the order to relaize these mizsions, we propose to use an inflatable, membrane,microstrip antenna that is particlularly suitable for low frequency science radar missions. IN order to mitigate risks assiciated with this revolutionary technology, the pace station demonstration will be very useful to test the long-term survivability o f the proposed amtenna. This experiment will demonstrate serval cirical technology challenges associated with space-inflable technologies. Among these include space-rigidization of inflatable strures, controlled inflation deployment, flatness and uniform separation of thin-film membranes and RF performqance of membrane microstrip an5ennas. This mission will also verify the inspace performance of lighweigth, high performance advanced SAR electronics. Characteristics of this SAR instrument include a cability for high resolution polarmetric imaging. The mission will acquire high quality acientific data using this advanced SAR to demsontrate the utility o f these advanced technologis. We will proesent an inflatable L-band SAR concept for commecical and science applications and a P-band design concept to validate the Biomass SAR mission concept. The ionospheric effects on P-band SAR images will also be examined using the acquired data.
