摘要
Abstract
Before tracking space targets by TT&C antennas,scanning of the predetermined airspace is required.To solve the problems of simple design,low scanning efficiency,and blind spots in current antenna scanning strategies,an improved spiral scanning strategy is proposed,which employs a combination of coarse and fine scanning with a spiral line centered on the pre-set waiting point of the target spacecraft.The antenna beam is controlled to sweep rapidly and coarsely over a large area in the expanding scanning stage,and to sweep finely over a small area in the contracting scanning stage,so as to realize fast and efficient scanning over a large area of the target's predefined searching airspace.Simulation results demonstrate that by using the improved scanning strategy,a larger scanning area is covered,the success rate of searching and capturing spatial targets is significantly increased in a short period,and smooth changes of antenna velocity can be realized,which is beneficial for protecting the mechanical structure of the antenna.关键词
