Abstract

The invention discloses a multi-parameter detection system and detection method based on spacecraft on-orbit space debris collision, wherein the debris collides with a capacitor array film and a metal plate to form an elastic wave, which is obtained by detecting the amplified signal of the capacitance and the elastic wave parameters to calculate the corresponding parameters for various fragments. The invention also discloses a corresponding detection method for key parameters of space debris. The invention can detect parameters such as fragment size, speed, flight direction, collision position, etc., and has the characteristics of higher sensitivity, and the accuracy of measurement results is higher, and the detection sensitivity can reach 0.1mm.

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...
