Electromagnetic Compatibility Effects on Antenna Pattern of Spaceborne SAR

Abstract

Due to the limitation of satellite size, electromagnetic compatibility (EMC) effects on the antenna pattern should be taken into account, especially in the case of small satellite platform. In this paper, the property of SAR antenna pattern is discussed firstly. Then, the effects on antenna pattern is studied and analyzed, which results in antenna pattern distortion. Moreover, considering the antenna pattern distortion, the influence on SAR image quality is present as well. Finally, simulations are performed to validate the effects caused by EMC.
