摘要
Abstract
The algorithm of phase gradient autofocus (PGA) is widely used in airborne SAR image formation. Because of its complexity and large data size, TS201 DSP with powerful processing capacity is selected to fit for the real-time airborne SAR. In order to make better use of TS201, the algorithm is optimized according to the theories of PGA and the characteristics of TS201 processors, and the most time-consuming FFT procedure is implemented by assembler, which minimizes the data size and the runtime. IDL Simulation and DSP testing system proved this scheme to be feasible for the autofocus of real-time SAR image formation.关键词
