摘要

星上定标器作为遥感卫星在轨辐射定标装置，定标漫反射板(SD)作为定标器中的参考标准板，其结构设计的可靠性将直接影响到星上定标器的定标精度。为了得到星上定标漫反射板结构在航天力学条件下的响应情况，通过振动实验台模拟对其进行加速度过载和随机振动响应特性进行了测试，获得了定标漫反射板组件的加速度过载响应特性、固有频率和随机振动响应特性。同时，为了考察星上定标漫反射板的光学特性，进行了方向半球反射比(DHR)、双向反射分布函数(BRDF)等光学特性的测量。结果表明，漫反射板组件在航天力学条件下强度和刚度都满足设计要求，基频大于120 Hz；而且漫反射板具备高反射率(大于99%)、光谱平坦性、朗伯性等优良光学特性，满足航天应用要求。

Abstract

Reflective solar bands are calibrated on orbit by a solar diffuser(SD) panel. The SD panel plays an important role in a set of on-board calibrator. Its reliability of the structure design will directly affect the accuracy of the on-board calibrator. In order to get the response situation of the calibration diffuse reflection plate structure under space mechanical condition, vibration test on SD panel is processed. In the test, the data on the frequency of the SD panel structure and the dynamic response are got by stochastic load test method. Meanwhile, the optical properties of the SD panel: hemispherical reflectance direction(DHR) and the bi-directional reflectance distribution function (BRDF) are measured. The results show that the frequency of the structure can meet the design requirements (more than 120 Hz), high reflectance(more than 99%), spectral flatness and good Lambertian scattering properties in reflectance, which are basic requirements for space applications.
