A ground test and in-orbit integrated verification method for satellite stealth performance

Abstract

The invention discloses a satellite stealth performance ground test and in-orbit integration verification method, and belongs to the technical field of spacecraft stealth performance testing. The method comprises the following steps that a stealth satellite is arranged to be in a non-stealth state and a stealth state, and theoretical simulating calculation is performed on the stealth performance of the satellite; stealth performance testing is performed for the non-stealth state and the stealth state of the satellite through ground microwave anechoic chamber test equipment; after the satellite is injected into an orbit, in-orbit comparative measurement is performed on the stealth performance achieved when the satellite is in the in-orbit non-stealth state and the stealth performance achieved when the satellite is in the in-orbit stealth state; quantitative evaluation is performed on the satellite stealth performance according to the specific indexes of the satellite stealth design by analyzing in-orbit satellite measurement data; comparative analysis is performed on theoretical simulating data, ground test data and in-orbit test data of satellite RCS sequence values. Accordingly, a specific technical scheme and a quantitative test analysis method are supplied to satellite stealth performance testing in future, and the method can be applied to radar stealth satellite platforms, optical stealth satellite platforms, infrared stealth satellite platforms and the like.

Description

[0001] Technical field: [0002] The invention relates to a method for ground testing of satellite stealth performance and on-orbit integration verification, belonging to the technical field of space vehicle stealth performance testing. [0003] Background technique: [0004] With the deepening of the militarization of space, as high-tech satellites and other space resources, they will increasingly face threats of "destroy", "blinding", and "interference". As an important reconnaissance tool and space weapon, the stealth satellite has the ability to conceal in orbit, reconnaissance and wait for an opportunity to attack the enemy. Therefore, in future wars, stealth satellites will play an important role in space attack and defense. The detection equipment for space targets mainly includes ground / sea-based radar for detection of low-orbit satellites and ground / space-based optical detection equipment for detection of high-orbit satellites. Therefore, the corresponding spatial stealth ...
