Abstract
The work aims to develop analysis methods for analyzing complex electromagnetic environment electromagnetic effects in different scenes of the attitude-orbit control engine construction.By decomposing the complex model of the atti-tude-orbit control engine layer by layer,electromagnetic sensitivity models were established based on the electromagnetic sensi-tive characteristics of each component-level model.Analysis was conducted from the system level,the complete machine level,the component level,the PCB board level to the device level to analyze the complex environment faced by the attitude-orbit control engine,and conduct layered analysis research on the electromagnetic characteristics of the attitude-orbit control engine.The electromagnetic environment scenarios faced by the attitude-orbit control engine were classified and divided into three main scenarios:ready-to-launch,mid-flight,and terminal engagement with the enemy.The interference sources under these three types of scenarios were classified,and the electromagnetic interference sources and sensitive bodies as well as the electromag-netic coupling interference matrix of the attitude-orbit control engine under the complex electromagnetic environments were identified.This study provides guidance for the stability and reliability research of the attitude-orbit control engine in complex electromagnetic environments,laying a solid foundation for further electromagnetic characteristics simulation and validation re-search.
