机载SAR目标信号模拟器的一种硬件实现

SAR echo simulator can support SAR system design and argumentation by supplying database, and presently it has become one of the most important means to debug and test the SAR system. The target signal generator is the most important and complex module of SAR echo simulator. This paper, first of all, introduce a hardware design of target signal generator for SAR echo simulator based on DSP(ADSP-203S), then illuminate the pivotal part of it, finally test the performance of the system by point echo simulation.
