A Tailoring Method for System-Level Radiated Emission Control Standards

Abstract

The invention discloses a tailoring method for system-level electromagnetic compatibility radiation emission control standards. In the early stage of system overall design, the overall layout of the system is known in advance, the characteristics of electric field radiation sensitive receiving equipment in the overall system design are mastered, and the parameters of these equipment are determined. The operating frequency band and sensitivity limit, as well as the gain of the receiving antenna of these radiation-sensitive receiving devices, are then calculated to obtain the amount that needs to be tightened on the electromagnetic compatibility radiation emission standard, so as to realize tailoring. By using the present invention, the electromagnetic compatibility radiation emission control standard of the corresponding radiation emission equipment can be formulated when the technical scheme is formulated at the initial stage of system design, and it can be kept in sync with the formulation of its stand-alone technical requirements, so that the radiation emission equipment can be completed at the initial stage of design Implementing the EMC radiation emission control requirements into the design scheme can quickly reflect the changes in the electromagnetic performance indicators of stand-alone equipment in the design process to the system and sub-system EMC radiation emission control standards, which is also beneficial to the overall Further grasp the degree of completion of the design goals, so as to achieve the control of the system electromagnetic compatibility safety margin and improve the reliability of the satellite.

Description

technical field [0001] The invention relates to a tailoring technology for radiation emission control standards, in particular to a tailoring method for system-level electromagnetic compatibility radiation emission control standards. Background technique [0002] Modern ocean dynamic environment satellites are microwave remote sensing satellites, whose main task is to monitor and investigate the ocean dynamic environment, including sea surface wind field, waves, currents, sea surface temperature, sea storms and tides, etc. In order to obtain high-precision remote sensing data, the satellite usually Loaded with many highly sensitive microwave load equipment, they have many types of operating frequency bands, covering almost all bands such as UHF, L, S, C, X, Ku, Ka, etc., and found potential electromagnetic interference within the 4th order in the frequency analysis of a certain initial sample development There are more than 10 types of pairs, the coupling paths of various in...

[0008] However, due to the unclear operation steps of these methods, the tailoring of standards is relatively random, which may lead to under-design or unnecessary over-design of radiation-emitting equipment

Due to the lack of guidance on the control of the electronic radiation emission characteristics of the single aircraft on the satellite based on the comprehensive analysis of the system tasks, it may lead to such a phenomenon: the satellite system has reached the limit requirements of the single aircraft test, but it still shows interference to other radiation-sensitive types in the electromagnetic compatibility test.
