针对高速飞行器气动加热效应对高速飞行器光学性能的影响，建立了防护罩热辐射模型。在此基础上，编写了仿真控制程序，利用TracePro软件，实现了光学自动追迹，动态模拟了防护罩热效应在整个光学系统扫描过程中产生的影响，以及在各光学运动部件单独扫描时的影响。通过对热效应引起的杂散光在玫瑰扫描过程中的传输路径分析，提出了建议改进措施，为高速飞行器光学性能分析及其环境失效研究提供了参考。

Aiming at the influence of the aerodynamic heating effect of the high-speed vehicle on the optical performance of the vehicle, the heat radiation model of the dome window of the vehicle was established. On this basis, the simulation control program was programmed, and the optical automatic tracing was realized by using TracePro software, and the thermal effect of the dome window produced during the scanning of the entire optical system, as well as the effects of individual optical moving parts when scanned separately were dynamically simulated. Through the analysis of the transmission path of stray light caused by thermal effect in the process of rosette scanning, the proposed improvement measures were obtained, which provided a reference for the optical performance analysis and environmental failure research of high-speed vehicle.
