Integrated System of Mini-SAR Real-Time Signal Processing and Control System

介绍了一种微型SAR实时信号处理和控制一体化系统及实现算法流程。该系统采用FPGA和ADSP-TS101混合处理的方式,提升了处理性能;并利用FPGA实现了传统控制系统功能,降低了系统重量和功耗,满足微型SAR系统的要求。并在飞行试验中获得实时处理图像,验证了系统设计的可靠性和算法的可行性。

An integrated system and the processing algorithm flow are introduced. The integrated system is composed of Mini-SAR real-time signal processing and control. By using of ADSP-TS101 and FPGA mixed processing, the system performance is improved. And also, this system proposed that conventional controls function is achieved in the FPGA makes weight and power consumption reduced to meet the needs of Mini-SAR. At last the obtained real-time SAR images during the flight experimentation verified the reliability and the feasibility of the integrated system.
