Method for analyzing electromagnetic interference of attitude and orbit control engine in complex electromagnetic environment

The embodiment of the invention relates to a method for analyzing electromagnetic interference of an attitude and orbit control engine in a complex electromagnetic environment. The method comprises the following steps: constructing an electromagnetic environment model of a to-be-launched state environment scene, an electromagnetic environment model of a lightning interference scene, an electromagnetic environment model of a body interference scene and an electromagnetic environment model of a tail section enemy state scene according to a typical complex electromagnetic environment of an attitude and orbit control engine; and analyzing electromagnetic weapon interference, countermeasure and non-countermeasure radiation interference, natural radiation interference and platform basic noise under each model. According to the embodiment of the invention, the test data after acquisition, recording and fusion processing are analyzed, and the evaluation result of the electromagnetic property of the tested equipment i
