Abstract:

This paper explores the relationship between inertial device error and synthetic aperture radar (SAR) image resolution in order to improve the performance and cost ratio of SAR motion compensation system. The relationship will help the researchers to develop the SAR motion compensation subsystem with corresponding precision. First this paper describes the solution and fixing way of SAR motion compensation subsystem, and then figures out the different influence of inertial device error (on different axes) on antenna position measurement precision.
