High resolution scatterometer based on vector network analyzer

Abstract

For the scatteroineter based on vector network analyzer Hp852Oc is used for High Resolution Radar clutter measurement. the system parameters must be redesign to fulfill the request. Relation exists among the range resolution. ininiinuin ambiguous range A d sample point number. and the scope of parameters is limited, so considemtion must be tmdeoff. At the Same time. with the range resolution rise. the illuminated area reduces. the return echo power would fall. so the equipment sensitivity or the nuxinium range must be consider too.In the paper the design procedure is introduced. One sea chitter ineasurement has been done by this project. It is found tlm o at lGHz bandwidth is greater than that at 0.2 GHz bandwidth when the grazing angle is less than 10 degree. The p r i m results show the project for high resolution viable.
