摘　　要：探讨了一种红外成像探测系统实时信号处理算法、硬件结构等关键技术.针对大视场红外探测系统,提出了适用于360°全方位红外目标搜索的实时处理算法原理和流程,并以高性能的数字信号处理器和FPGA芯片以及CPC I总线技术为核心设计了处理能力强、高速数据传输、接口可靠稳定的实时信号处理系统.实验测试表明,该系统工作稳定、可靠,满足总体性能要求.The basic technology real-time signal processing arithmetic and hardware architecture of infrared image detecting system were presented. Aiming at a large view field infrared detecting system, the real-time processing arithmetic principle and flow, which are applied to omnidirectional infrared target search, were proposed. The scheme of applying high-performance DSP, FPGA and CPCI bus technology was used to compose a signal processing system which has powerful processing capability, high-speed and reliable interface, The experimental result shows that the large field infrared image detecting real- time signal processing system works reliably and stably, and it has achieved the demand of high performance.
