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.
