Experimental Demonstration of Ku-band FMCW Automobilebased SAR in Stripmap Mode

Abstract

This paper introduces a Ku-band frequency modulated continuous wave(FMCW) automobile-based synthetic aperture radar(SAR) system to attain ground SAR image. The architecture and the specification of the FMCW SAR system are mentioned to verify the notable performance. The modified range doppler algorithm(RDA) is used to acquire clear image in order to be suitable for the FMCW radar system and the automobile-based platform. We had gathered the raw data moving in constant velocity on highway. The validity of the proposed FMCW radar system to process SAR image is demonstrated in the practical results.
