System and method for ground test of multi-dimensional dynamic optical characteristics of space target

Abstract

The invention relates to a space target multi-dimensional dynamic optical characteristic ground test system and method. The system comprises a spherical container, a solar simulator placed on the topof the spherical container for simulating the solar radiation of the space in which the target is located, a three-dimensional motion simulator placed inside the spherical container for carrying the target and simulating pitch, yaw and spin attitude motions of the target, a background radiation simulator placed under the three-dimensional motion simulator for simulating the background radiation inthe space where the target is located, an omnidirectional test track located on the meridian plane of the spherical container, a measuring device arranged on the omnidirectional test track for movingalong a meridian direction, multiple optical characteristic observation windows and measuring devices located in different directions on the equatorial plane of the spherical container for measuringnear-field optical characteristic data of the target and a clear optical path cylinder communicated with the spherical container with the tail end provided with a measuring device for measuring the far-field optical characteristic data of the target.

Description

technical field [0001] The invention relates to space target simulation test technology, in particular to a space target multi-dimensional dynamic optical characteristic ground test system and method. Background technique [0002] When a spacecraft flies in space, it is usually combined with natural optical environments such as space and the sun. In the prior art, ground tests are usually used to simulate the optical characteristic changes of space targets. However, the equivalent heat flow simulation and the measurement of the optical properties of a single-direction target are usually used, which cannot effectively simulate the multi-angle dynamic changes of the target in the geometric scene. [0003] Therefore, it is urgent to provide a ground test system and method for multi-dimensional dynamic optical characteristics of space targets to realize the dynamic optical characteristics of space targets on the ground. Contents of the invention [0004] The purpose of the p...
