Abstract

The invention provides an electromagnetic pulse composite effect test method and system in a space environment. The method and system are used for accurately obtaining a high-power electromagnetic pulse composite effect threshold of a target in the space environment. A space environment simulation means (having environmental capabilities such as space particle environment simulation, space high-low temperature environment simulation and space vacuum environment simulation) acts on an object, so that the object is in a space environment condition; meanwhile, a high-power electromagnetic pulse signal (which can be one or a combination of more of narrow-band high-power microwave HPM, ultra wide band electromagnetic pulse UWB, broadband electromagnetic pulse wideband, lightning electromagneticpulse LEMP, nuclear electromagnetic pulse NEMP and electrostatic discharge ESD) is loaded in an irradiation or injection mode; finally, online monitoring is conducted on the test object through detection equipment, a high-power electromagnetic pulse composite effect threshold value in the space environment is obtained, and then threshold value data and rules are accurately obtained.

Description

technical field [0001] The invention belongs to the field of electromagnetic field and microwave technology, and specifically relates to an electromagnetic pulse compound effect test method and system in a space environment. Background technique [0002] In the high-power electromagnetic pulse effect technology, the effect threshold and damage mechanism are the most critical data content. However, the current high-power electromagnetic pulse effect test is only carried out in the conventional environment on the ground, without considering the environmental conditions of space vacuum, high and low temperature, and particle irradiation. System technical design and applicability. [0003] There are following shortcomings in this method: [0004] 1. The accuracy of the damage threshold. The space irradiation environment will lead to electrification of the space test object, and the vacuum environment is not conducive to the heat dissipation of the target. These factors will i...
