红外制导系统中的点目标检测技术

On the Detection of Point Target in IR Homing System

本文讨论红外自动寻的末制导系统中的点目标检测问题，文间分析了点目标检测的难点及可能解决问题的途径，并基于目标轨迹的连续、平滑特性提出了一种利用构造总代价函数并使之最小从而实现对点目标检测的非线性方法。针对匀速运动和匀加速运动两种轨迹的不同特性具体推导了两种检测算法，最后，对检测器统计检测性能进行了估算。

Based on the continuity and smothness of target tracks in the image sequence,and non-lin-ear detection scheme which transfer the problem of detection to the problem of miniminimizing an overall cost function is formulated.Two algorithms corresponding to track of maneuvering as well as non-maneuvering targets are discussed in detail. The detection performance is also estimated.
