基于红外特性的弹道导弹助推段预警探测能力仿真

Simulation of Early Warning and Detection Capability of Ballistic Missile in Boosting Phase Based on Infrared Characteristic

针对弹道导弹助推段的主要红外辐射特征,分析了尾焰羽流的结构、形状、大小和持续时间,以及大气对红外探测的影响;根据预警卫星探测器最大作用距离模型及信噪比(SNR),结合给定参数对预警卫星探测器技、战术指标进行了仿真,给出了提高弹道导弹探测能力的方法。

Aiming at the main infrared radiation characteristics of ballistic missile in boosting phase,this paper analyzes the structure,shape,size and lasting time of exhaust plume and the influence of atmospheric on infrared detection;according to the maximum operating range model and signal-to-noise ratio（SNR）of early warning satellite detector,simulates the technical and tactic index of early warning satellite combining with the given parameter,gives the method to improve the detection capability of ballistic missile.
