| Abstract: | This paper analyzes detailly the motion effect in a satellite borne synthetic aperture radar(SAR). The general relations for the echoes Doppler parameters and range migration properties in stellite borne SAR are given. The effect of satellite's motions on Doppler parameters and images is proven in detail. and the quantitative representations for satellite motion velocity errors, acceleration errors, and attitude errors have been derived. The motion errors processing methods are also discussed. |
