摘　　要：文章针对复杂背景下红外小目标检测中实时性和算法复杂性的问题，硬件设计方面采用基于FPGA＋DSP架构，其中FPGA作为协处理器，DSP作为主处理器，实现实时高效的检测系统。软件算法上FPGA完成图像预处理算法，DSP实现目标识别等核心算法。通过软硬件优化设计，实验证明单帧图像处理速度大大提高。To resolve the problems of real-time and complex algorithm for weak IR target detection under compli- cated background, the structure based on FPGA ＋ DSP is adopted by hardware design, which can realize the high efficiency and real time detection system. The FPGA is a coprocessor, the DSP is a main processor. The im- age preprocessing algorithm is completed by FPGA and target identification algorithm is completed by DSP. The experiment verifies that the processing speed of single-frame image is improved significantly via the optimum design of software and hardware.
