目标图像运动特征分析

Target Image Motion Characteristics Study for Imaging Seeker

在红外成像导弹导引头的信息处理中,目标图像特征研究是导引头技术研究中的一个重要问题。对各种潜在目标成像特征的详细研究是红外成像导引头信息处理研究的基础。在此项工作完成的基础上,可以实现对导引头目标识别和跟踪算法的评价,同时也可以辅助图像处理算法的选择和优化。在分析红外成像制导空空导弹工作原理的基础上,建立了导弹、目标的仿真模型,对常见的目标图像运动特征进行了仿真分析。给出了在空战条件下目标图像运动特征的部分仿真结果。

Motion of the image presented to an imaging infrared(IIR)seeker blurs the incoming energy and degrades the systems ability to detect or recognize the distant targets.Effects of image motion on the performance of IIR seeker are important factors for seeker design and evaluation.A set of simulatiion model of missiles and targets were established.The motion characteristics were computed and showed.The results were used for the design of algorithm of target recognition and tracking.
