Study on the Electromagnetic Interference of SAR System to Wireless Power Transfer System

Abstract

Synthetic Aperture Radar (SAR) has attracted the attention of global radar scholars in recent decades due to its all-weather, high-resolution working mode. As an electromagnetic transmitting and receiving device, SAR system will produce electromagnetic interference to satellite airborne equipment. The wireless energy transmission system is a new type of satellite power supply equipment. Its transmitting and receiving coils are exposed in space, so it is easy to receive the electromagnetic interference from the SAR system. In this paper, the coupling circuit model of SAR system and WPT system is established, and the calculation and simulation show that the WPT system is robust enough so that the electromagnetic interference of SAR system to WPT system in high frequency band is retrieved and can be ignored.
