摘　　要：运用雷达上经典的自适应恒虚警的检测方法,分析红外图像特性,针对红外目标特点,结合FPGA的优势实现对红外视频图像目标的快速检测。兼顾了实时性、处理速度、系统可靠性等要求。外置可调谐式阈值设置,可适应多环境问题。实验结果表现出较好的效果,展现出较高的实用价值。The classical radar CFAR detection methods are used and the characteristics of image and infrared target features are analyzed to realize the target detection of infrared video image, which combine with the advantages of FPGA. The real-time, processing speed, system reliability and other requirements are taken into account in this method. The external threshold settings can be tuned, which is adapted to all kinds of background. The experi- mental results show very good effect and high practical value.
