弹道导弹弹道中段和再入段弹头红外光学识别方法研究

Research on infrared optical recognition methods of ballistic missile′s seeker during middle course and re\|entry phase

弹道导弹为实现有效的突破反导防区而不被防御系统拦截，在其弹道中段和再入段采用了多种突防措施，以免受反导系统的搜索、跟踪和识别。反导系统对于来袭弹道导弹弹道中段及再入段的识别可以用微波雷达技术，也可用光学技术。文中主要讨论用红外光学技术设备，通过对目标的温度、辐射强度、红外热图的测量进行目标识别的原理和方法，给出了一些分析计算结果。

In order to achieve effective breaking through the enemy′s anti\|missile defense theatre and avoid intercepted by anti\|missile defense system, many breakthrough methods have been implemented in middle course and re\|entry phase of ballistic missile to protect the missile from acquisition, tracking and recognition by anti\|missile system. In this paper, the principles and methods of target recognition are discussed mainly, using infrared optical technical equipment through the measurement of the target′s temperature, radiant intensity and infrared thermal image. Some analytical calculation results have been given. \;
