衛(wèi)星偵察在復(fù)雜電磁環(huán)境下的感知效果影響分析

Effects of complex electromagnetic environments on the perception of satellite reconnaissance system

摘要: 復(fù)雜電磁環(huán)境下，衛(wèi)星偵察設(shè)備的工作方式都是依賴電磁波的傳播,，其感知的準確性不同程度地受到電磁干擾的影響,。文章從復(fù)雜電磁環(huán)境的本質(zhì)出發(fā)，重點分析了人為形成的幾類電磁干擾,，包括對衛(wèi)星電子偵察,、光學(xué)成像偵察、雷達成像偵察和衛(wèi)星導(dǎo)航定位的干擾以及干擾應(yīng)對措施,，為最大限度減少復(fù)雜電磁環(huán)境對衛(wèi)星感知的干擾提供了參考,。

Abstract: As the satellite reconnaissance equipment is relied on the electromagnetic wave transmission, its accuracy is affected by the impact of electromagnetic interference (EMI) in various degrees. This paper analyzes the complicated electromagnetic environment, focusing on the effects of several types of artificial electromagnetic interferences on satellite electrical reconnaissance, optical and SAR imaging, and satellite navigation. Some propositions for anti-jamming are given.
