Embodiment Construction

[0033] The satellite stealth performance ground test and on-orbit integrated verification method of the present invention comprise the following steps:

[0034] (1) Set the stealth satellite to non-stealth state and stealth state, and simulate the two states, and calculate the theoretical stealth performance simulation data (such as theoretical radar cross-sectional area value, etc.) under different roll angles of the satellite;

[0035] (2) Through the ground microwave anechoic chamber test equipment, test the satellite's non-stealth state and stealth state respectively, and obtain the ground test data of the satellite's stealth performance;

[0036] (3) After the satellite is in orbit, 6 sets of comparative measurements are made on the non-stealth state and the stealth state of the satellite in orbit, so as to evaluate the actual effect of the satellite stealth design;

[0037] (4) According to the satellite in-orbit measurement data obtained in step (3), according to the sp...

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

Technical field: [0001] The invention relates to a method for ground testing and on-orbit integrated verification of satellite stealth performance, and belongs to the technical field of space vehicle stealth performance testing. Background technique: [0002] With the deepening of the militarization of space, space resources such as high-tech satellites will increasingly face threats such as "destruction", "blinding" and "jamming". As an important reconnaissance tool and space weapon, the stealth satellite has the ability to conceal, reconnaissance and attack the enemy in orbit. Therefore, in future wars, stealth satellites will play an important role in the attack and defense of space. The detection equipment for space targets mainly includes ground-based / sea-based radar for low-orbit satellite detection and ground-based / space-based optical detection equipment for high-orbit satellite detection. Therefore, the corresponding space stealth measures are mainly divided into t...
