摘　　要：介绍了一种高性能红外实时信号处理系统的原理、结构和特点。针对红外探测系统,提出了DSP+FPGA+CPCI的信号处理架构,采用VirtexⅡPro FPGA实现非均匀性校正等图像预处理,SpartanⅡFPGA实现CPCI总线技术,DSP64X实现高层目标检测算法,以构成处理能力强、高速数据传输、接口可靠稳定的信号处理系统。实验测试表明,这种实时信号处理系统工作稳定、可靠,满足系统性能指标要求。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.
