Abstract：Allowable platform motion error allocation is an important part of system-wide allocation in SAR system. It is a necessary system design procedure to take into account error effects, error sources, and performance-limiting factors to determine more reasonable design. Based on analysis and simulation of impact of platform motion errors on SAR image quality, a method is proposed of allowable platform motion errors allocations in airborne SAR system. Firstly, according to actual imaging system and environment, simulation mode is built; and then allowable self-existent motion errors, allowable coexistent motion errors, modified allowable motion errors are in turn obtained; finally, considering some associated factor, reasonable project is decided. As the method counts in platform and image parameter values, type and direction of platform motion errors and scene size, it has both pertinence and rationality.
