Abstract

The invention discloses a spacecraft-based on-orbit space debris collision multi-parameter detection system and a spacecraft-based on-orbit space debris collision multi-parameter detection method, which are characterized in that debris collides with a capacitor array film and a metal plate to form elastic waves, and corresponding parameters of various debris are calculated by detecting capacitanceand parameters obtained after signal amplification of the elastic waves. The invention further discloses a corresponding space debris key parameter detection method. According to the invention, parameters such as debris size, speed, flight direction, collision position and the like can be detected, the sensitivity is higher, the precision of the measurement result is higher, and the detection sensitivity can reach 0.1 mm.

Description

technical field [0001] The invention belongs to the technical field of spacecraft structural health parameter detection. Specifically, the invention relates to a multi-parameter detection device for collision of space debris in orbit of a spacecraft, and also relates to a multi-parameter detection method for collision. Background technique [0002] With the continuous development of the aerospace industry of various countries, the number of debris in the space field is increasing day by day. The existence of these debris directly threatens the safe operation of spacecraft in orbit. Although after years of technological development, the protective materials and protective structure design of the spacecraft have been greatly improved, which can effectively protect small-volume debris, but the protection effect on centimeter-level or even millimeter-level debris is limited. Real-time monitoring is carried out to obtain parameters such as debris size, speed, flight direction, an...
