Abstract

The EMC margin test method of the space-borne receiver, the EMC margin of the space-borne receiver is obtained in the stand-alone test stage, and the electromagnetic compatibility between the space-borne receiver and other electronic equipment of the satellite can be predicted in advance according to the test results, and the EMC control of the single-machine on the satellite can be guided , to avoid missing the opportunity of design modification. It can be used for system-level electromagnetic compatibility prediction analysis of the whole star, guide the EMC performance control of other electronic equipment on the star, and avoid the phenomenon of electromagnetic incompatibility of the whole star.

Description

technical field [0001] The invention relates to a test item and method in the electromagnetic compatibility test of space-borne electronic equipment, in particular to an EMC margin test method of a space-borne receiver. Background technique [0002] EMC margin is one of the important indicators to evaluate the electromagnetic compatibility of a system. It is the ratio of the sensitivity threshold of the key equipment of the system to the actual interference value, which can be expressed as M dB = S dB -I dB , where: M dB represents the system margin, S dB Represents the sensitivity threshold of the system, I dB Represents the actual electromagnetic interference value of the system. When S dB > I dB when M dB >0, it can be considered that the system can work compatible; when S dB ≈I dB when M dB ≈0, it can be considered that the system is in a critical working state; when S dB <I dB when M dB <0, it is considered that the system may not be compatible...
