红外系统探测巡航导弹的方法研究

从国外红外探测系统在巡航导弹探测以及应用方面的现状出发,分析了巡航导弹的红外特性和远距离条件下的成像特征,估算了红外探测系统对点目标作用距离。提出用并行差分滤波器去除背景,用逻辑与剔除噪声,用递归方法累积目标轨迹的算法。实验结果与分析表明基于差分基础上的逻辑与方法对速率>0.2像素/帧的目标具有较好的检测效果。

Detecting Cruise missile's Algorithm with Infrared Imaging System

The paper describes the overseas IR detection system and its applications.It analyzes the infrared and imaging characteristics in far distance of the cruise missile,and estimates distance by using IR image system to detect the point target.It proposes using parallel difference filters to suppress backgrounds,using logic AND method to eliminate noise and using recursive method to cumulate the target tracks.The result shows that it has positive effects on detecting the target whose velocity is above 0.2 pixels per frame.
