Satellite optical camouflage method

Abstract

The invention discloses a satellite optical camouflage method. The satellite optical camouflage method comprises the steps that a customizing task of a luminosity curve needing a satellite to displayin an observation segmental arc is received; positions of the sun and a detector in a satellite centroid orbit coordinate system in the observation segmental arc is resolved and calculated; the direction of an angular bisector of a sun position vector and a detector position vector in the observation segmental arc is resolved and calculated; the number of normal directions of surface panel sand needing to turn to the direction of the angular bisector of the sun position vector and the detector position vector at the time in the observation segmental arc at all time is determined, wherein the surface panels are installed on the surface of the satellite; and a determined number of the surface panels are turned to the direction of the angular bisector of the sun position vector and the detector position vector, and the normal directions of a rest number of the surface panels are made to deviate from the direction by more than 30 degrees. According to the satellite optical camouflage method, the problem that a high orbit satellite avoids ground optical monitoring is solved, by covering the satellite surface with special secular reflection characteristic material surface panels, the reflection direction of the surface panels is controlled, and simulation on the detection of the customized detector for the luminosity curve of a target is achieved.

Description

technical field [0001] The invention relates to a method for satellite optical camouflage, which belongs to the computing field. Background technique [0002] Satellite stealth is to take technical measures to reduce the monitoring possibility of satellite microwave, infrared, and visible light detection equipment in response to the detection threats faced by satellites in orbit. The purpose of satellites in orbit is difficult to be found, difficult to be hit, and difficult to be destroyed. [0003] Optical stealth is mainly divided into two types: material stealth and shape stealth. Material stealth is to reduce the probability of detection by using infrared control material or visible light reflection control material, so as to realize satellite stealth; shape stealth design is to change its structural characteristics so that Monitoring equipment mistook it for space junk or debris, etc. [0004] Due to the particularity of the satellite’s in-orbit space operating enviro...

AI Technical Summary

Problems solved by technology

[0004] Due to the particularity of the satellite’s in-orbit space operating environment and the limitations of the types of materials commonly used on the surface of space targets, the research on optical stealth satellites at home and abroad starts with the target’s macrostructure, which makes the mission function of the satellite itself greatly affected by the satellite’s stealth design. The design needs to redesign the matching platform type, and the macro stealth design is formed at one time, the stealth process is still relatively passive, and it cannot be actively adjusted according to the actual task to achieve intelligent "transformation"
