Experimental measuring method and measuring device for interaction between laser and space debris

Abstract

The invention relates to an experiment measurement method and device for laser and space debris mutual effect. The measurement method comprises the following steps of making preparation, namely arranging space debris in a spatial simulation vacuum experiment cabin to enable the space debris to be in vacuum, cold-back and suspended motion states and meanwhile starting a debris motion state measuring system; performing action, namely irradiating laser to the space debris in a one-time, multiple-time or continuous mode to enable the motion states to be changed after the space debris is stressed, meanwhile enabling the debris motion state measuring system to observe and calculate the motion states of the space debris in real time; processing data, namely processing, analyzing and outputting the data. By means of the experiment measurement method and device, the mutual effect process of the laser and the space debris can be really reflected, a three-dimensional six-freedom-degree motion track of the space debris is measured, and mechanical characteristic of the mutual effect of the laser and the space debris is inversed.

Description

technical field [0001] The invention relates to the field of aerospace technology, in particular to an experimental measurement method and a measurement device for the interaction between laser and space debris. Background technique [0002] Space debris is space junk produced along with human space launch activities. It is a general term for man-made objects and their fragments without any function and function in earth orbit (altitude about 200-36,000 km). Space debris is widely distributed and the number is huge. There are about 20,000 space debris larger than 10cm that have been cataloged, and the number of centimeter-sized or smaller space debris is as many as tens of millions. The existence of space debris seriously threatens the safety of orbiting spacecraft, and the continuous generation of space debris also poses a serious threat to limited orbital resources. At present, laser is recognized as a potential and feasible means of detecting and removing space debris, w...

AI Technical Summary

Problems solved by technology

In order to ensure the measurement accuracy, the damping device must be used to keep the space debris as still as possible before each experiment, so only the effect of a single laser pulse can be measured, and it is impossible to obtain the effect of multiple pulses continuously irradiating space debris in actual conditions, and Since space debris is fixed on the measurement system, only the mechanical characteristics of space debris along a specific direction can be measured, and the actual process of laser-space interaction cannot be simulated
