基于辐射特征的干扰弹检测方法研究

根据干扰弹在起燃时间内辐射能量急剧增加的特点,利用图像序列中图像灰度斜率的突变进行干扰检测是一种比较有效的方法。利用仿真选择有效的数据平滑方法对灰度变化斜率进行估计,以消除焦平面探测器采样特性和噪声的影响,定量分析了影响干扰弹检测概率的各种因素,评价了利用辐射特征检测干扰弹的优点与不足。

Study on Decoy Detection Method Based on Rise Time

Detection of the decoys in the FOV of the imaging2infrared seeker ( IIR) is important for IIR to track the true target aircraft . It is not an easy thing when the target image only has several pixels. One of the most effective discriminations in IIR is rise2time characteristic of the decoy. A practical data smoothing method is used to eliminate the sampling effect and noise. The relative factors ,which affect the decoy detection probability ,are analyzed.
