          Abstract

          Attitude Steering has been widely applied to the current low orbit SAR system to decrease the rang/azimuth coupling of the received data. This paper focuses on the impacts of attitude steering to the observation properties of Geo-SAR, namely, Doppler parameters, range swath, and rang cell migration effect, and a comparisonbetween 3 different ways of attitude steering is made. Based on the simulation results, the necessity of attitude steering for Geo-SAR is validated, and for Geo-SAR on elliptical orbit, 2D attitude steering is the most effective.
