[0063] Embodiment 2. Another aspect of the present invention also provides a method for measuring the impact damage process of a flying target, which is implemented based on the measuring device for the impact damage process of the flying target. The measurement method includes:

[0064] Lay the orthogonal metal mesh on the flying target, use the first level signal to supply power to the orthogonal metal mesh, monitor the level signal change of each metal wire in real time, and record the level signal in time sequence from the first level signal The number of metal wires falling to a low level below the second level signal determines the instantaneous damage position and instantaneous damage size of the target according to the change of the metal wire level signal.

[0065] The first level signal can be a 5V level signal, and the second level signal can be set according to empirical values ​​or determined through experiments, for example, a low level below 0.4V.

[0066] The b...

Abstract

The invention relates to a measuring device and a measuring method of impact damage process of a flying target. The measuring device comprises an orthogonal metal mesh, a horizontal electrical signalprocessing module and a vertical electrical signal processing module, wherein the orthogonal metal mesh is arranged on the surface of a target; the horizontal electrical signal processing module is used for monitoring each horizontal metal wire level signal in a horizontal metal wire array, and determining the number and breaking time of a broken horizontal metal wire according to the change timing sequence of the level signal; the vertical electrical signal processing module is used for monitoring each vertical metal wire level signal in a vertical metal wire array, and determining the numberand breaking time of a broken vertical metal wire according to the change timing sequence of the level signal. According to the measuring method disclosed by the invention, the broken wire at certainmoment is judged through the on-off of a metal wire electrical circuit in the metal mesh; the position and the size generated by impact of space debris on the flying target can be determined according to the broken wire constructed space determined at the same sampling time.

Description

technical field [0001] The invention relates to the field of impact damage measurement of flying targets, in particular to a measuring device and method for impact damage process of flying targets. Background technique [0002] With the rapid development of human spaceflight, space debris (space junk abandoned by humans, micrometeoroids, etc.) is increasing day by day. When space debris hits a spacecraft, it can damage the outer shell at least, or cause malfunction or even disintegration and damage at worst. Therefore, it is necessary to measure in real time the area where a target such as a spacecraft is hit by an incoming object such as space debris to assess the damage to the target, and also provide support for analyzing the size and velocity of the incoming object. [0003] At present, in order to meet the needs of spacecraft in orbit to measure the impact damage of space debris, a wire mesh measurement method is adopted. This method is to obtain the impact position an...
