羽流对卫星反射面天线辐射特性的扰动分析
Analysis of satellite reflector antenna radiation characteristics perturbed by plume
摘要
Abstract
The electric thruster has the advantage of high specific impulses and requiring much less fuel compared with the chemical thruster,and it will improve the mobility and life span of a satellite.Electromagnetic waves will be attenuated in the plasma plume because of absorption and refraction effects.In this paper,Ray tracing,aperture integral and the superposition principle of the electric field are used to analyze the effects of the plasma plume on antenna performance.The attenuation of the plume between 2GHz and 5GHz frequencies are calculated.For a 20cm electric thruster plume,simulation results vary from 0.3dB to 2.5dB compared with the experimental data,and the angle of the main lobe bending away from the thruster is less than 0.5 degree for the E-plane pattern.关键词
