美国国防支援计划预警卫星红外有效载荷的光学仿真

Optics Simulation of the Payload of U.S Defense Support Program(DSP) Satellites

为准确估计美国国防支援计划(DSP)预警卫星的性能参数,在对DSP卫星红外有效载荷技术分析的基础上,对其光学结构和参数进行分析和仿真,得到视场、弥散斑半径、能量集中度、传递函数等关键特性,可为DSP卫星和后续天基红外预警卫星(SBIRS)的探测性能开展有效仿真提供有效支撑。

To evaluate the detectability of U. S DSP early-warning satellite accurately, the optics simulation and analysis are designed for the optics structure and parameter of infrared payload. With the result parameter such as filed view, dispersion spot distribution, focus ability, MTF etc. , the simulation for detectability of DSP and space-based infrared system（SBIRS） will be supported effectively.
