NGSO星座与GSO卫星间的干扰规避波束规划方法
Interference avoidance beam planning method between NGSO constellation and GSO satellite
摘要
Abstract
With the rapid expansion of NGSO(non-geostationary satellite orbit)constellation systems,spectrum resources have become increasingly congested.To address the issue of spectrum sharing between NGSO and GSO(geostationary satellite orbit)systems,an interference-avoidance beam planning method for spaceborne phased array antennas based on spatial isolation zones was proposed.By analyzing interference scenarios between NGSO and GSO systems,the Earth's surface was discretized into a grid based on latitude and longitude for uniform spatial enumeration.A time-sliced aggregate interference analysis model was then established to assess the interference from NGSO systems to segments of the GSO arc.Based on the interference-to-noise ratio threshold criterion,an optimization objective for phased array antenna beam planning was formulated to facilitate spectrum sharing between NGSO and GSO systems.Furthermore,the mapping mechanism between spatial isolation zones and beamforming strategies was elucidated,leading to the proposed method for interference-avoiding beam planning.Simulation results validate the effectiveness of the approach,offering a valuable reference for the design and implementation of LEO(low Earth orbit)satellite constellations.关键词
