摘　　要：文中分析了地面背景下目标和背景的红外辐射特性,给出了目标在理想状态和实际状态下的探测概率,指出在目标探测系统的设计中,应提高光学系统的设计,减少衍射、像差和色差带来的像斑弥散。同时本文设计了红外目标探测跟踪系统的硬件电路,对软件设计中的数字图像滤波算法进行理论分析和计算,实现了远距离红外地面目标的实时检测和跟踪。Probability detection of infrared target is indicated in perfect state and practicality state by analyzing the infrared radiant characteristic of target and background in surface background. The text point out it while surveying the systematic design in the goal, must rise the design of the optical system, reduce the picture spot dispersion that aroused by diffraction and aberration. At the same time, the article provide the principle block diagram of target detection and tracking system design, introduce two digital filter the waves of certain frequencies mainly. Choosing the high performance digital signal processor TMS320C6416 to calculate the differing information of infrared goal at percent and realize the goal measured and followed in real time.
