Current Situation and Development Trend of Inflight Antenna Pattern Measurement Techniques of Spaceborne SAR: Current Situation and Development Trend of Inflight Antenna Pattern Measurement Techniques of Spaceborne SAR

Abstract

Abstract: The antenna pattern uncertainty is the main error of Synthetic Aperture Radar (SAR) system. The technique for inflight antenna pattern measurement of spaceborne SAR is one of the most important technique of SAR calibration. This paper discusses the development courses of the inflight antenna pattern measurement of spaceborne SAR, analyses its development trend and compares the main inflight antenna pattern measurement techniques. This paper will be an important reference for designing a project of inflight antenna pattern measurement of spaceborne SAR.
