中继卫星空间静态波束的构建方法OA北大核心CSTPCD

Through the wide-area coverage of the static beams in space,the time efficiency and multi-target capability of the tracking and data relay satellite measurement and control service will be effectively improved.A method for constructing the space static beams of the tracking and data relay satellite was proposed.The space static beams construction was realized by the phased array antenna of the tracking and data relay satellite and multiple ground computing units on the basis of the principle of digital beam forming.The simulation analysis of the spatial static beams configuration was carried out from the angles of different beam overlap and different space heights.The result shows that it is necessary to make a compromise between satellite beams coverage and the number of ground computing units,so as to maximize the performance advantages of the tracking and data relay satellite space static beams in engineering application.
