| 摘 要： | 为改善弹道导弹再入段地面红外探测效果，考虑导弹再入过程中气动加热、红外辐射的大气衰减以及背景辐射等因素，建立起弹道导弹再入段地面红外探测仿真分析模型，并估算分析了探测系统在不同状况下信噪比.分析结果表明：优选工作波段、增加系统口径及曝光时间、改善光学设计、选择晴朗无云天气观测等均有利于改进地面红外观测效果.

| Abstract: | To improve ground infrared detection, the infrared detecting simulation model of ballistic missile in re-entry is established, considering the aerodynamic heating of missile in the re-entry, the infrared radiance attenuation in atmosphere, and background radiation noise. The SNR system is analyzed with different conditions. The results indicate that by selecting working band, increasing the system aperture and exposing time, improving the optical design, and selecting the cloudless weather for observation will improve the effect of system. |
