凝视型红外搜索跟踪系统对巡航导弹作用距离分析

Analysis on operating range of the staring infrared search and track system for cruise missile

红外探测系统对巡航导弹进行探测预警,是拦截巡航导弹的首要条件。通过分析在3-5μm波段内,作为巡航导弹主要辐射源的蒙皮、发动机喷口和羽流的红外辐射特性,建立了凝视型红外搜索跟踪系统（IRST）对巡航导弹的作用距离模型,给出了求解距离方程的正确方法,并对实例计算的结果进行了分析。

Warning and detecting cruise missile by infrared detection system is the first condition of intercepting cruise missile. The infrared radiation characteristic in 3 - 5μm spectral band of the cruise missile from three major IR radiation sources, including the missile skin, engines vents and air current-flame were analyzed. The operating range model of a staring IRST system for the cruise missile was established. The correct methods of solving the operating range equation were given,and the computed result was analysised.
