| Abstract: | The principle, structure and characteristics of a high-performance infrared realtime signal processing system are introduced. Aiming at infrared detecting system,the framework of signal processing system including DSP,FPGA and CPCI is proposed. The scheme of applying Virtex H Pro FPGA to realize nonuniformity correction pretreatment,applying Spartan H FPGA to realize CPCI bus, and applying DSP64X to realize high-level target-detecting arithmetic, has composed a signal processing system which has powerful processing capability, high-speed and reliable interface. The experimental result shows that the real-time signal processing system works reliably and stably,and meets the requirement for high performance system. |
