摘要
Abstract
The main magnetic source distribution characteristics of low﹣orbit microwave remote sensing spacecraft is analyzed and some effective craftwork measures and design methods for re﹣ducing spacecraft stray magnetic moment is put forward according to the subsystems diversity such as large power capacity onboard TR components,active antenna array,electric power supply and SAR,supply current circuit,ground current circuit which may induce lager stray magnetic moments?The test results shown that the total static permanent magnetic moment,dy﹣namic stray magnetic moment can be greatly reduced with reasonable ground connection of the whole spacecraft,miniaturation of TR components and active antenna array,as well as rational layout of the harness?The resulted magnetic moment is up to the required specifications?关键词
