Problems solved by technology

[0003] However, with the development of deep space exploration, the detection complex is composed of multiple monomers, such as upper poles, detectors, landers, and returners. Each monomer in the complex is equivalent to a satellite and can be tested independently , complete the corresponding task independently, because the independence of the single detection unit is strong, it will reduce the joint test time, making the electromagnetic compatibility problem more prominent

Abstract

The invention provides an EMC (Electro Magnetic Compatibility) test method of a deep space aircraft coupling. The method comprises the following steps of: turning off power of each detector consisting of the aircraft coupling, calibrating EMC test equipment, and testing the background noise of an anechoic chamber; carrying out the electromagnetic radiation and sensitivity test on each detector; analyzing test data of each detector; determining the suppression condition of mutual interference between detectors of the aircraft coupling; and carrying out the EMC test on the aircraft coupling. For the source of electromagnetic interference, by adopting a test method from the point to the surface, the EMC characteristics of the deep space aircraft couplings can be quickly, reliably and safely detected, the source of electromagnetic interference is determined, the electromagnetic interference and the failure are safely and reliably detected, and the EMC test efficiency of the deep space aircraft coupling is improved.

Description

technical field [0001] The invention relates to an EMC test method, in particular can be applied to the EMC test between deep space probes and large complexes, and in particular relates to an EMC test method for deep space aircraft complexes. Background technique [0002] At present, GJB151A-97 "Electromagnetic Emission and Sensitivity Requirements for Military Equipment and Subsystems" and GJB152A-97 "Electromagnetic Emission and Sensitivity Measurement for Military Equipment and Subsystems" are used for EMC testing in the aerospace field. These two standards clearly stipulate that they are used for individual military equipment and subsystems, and there is no clear regulation for electromagnetic compatibility between multiple military equipment and complexes. In the past, for earth satellites, the EMC test was aimed at each single unit inside the satellite, and did not consider the EMC characteristics and corresponding test methods for multiple detectors as a whole.
