摘要
Abstract
Near-space Telemetry,Tracking and Commanding（TTC） communications are of great importance in military applications.Due to the existence of dynamic,wide-range multipath fading and Doppler frequency shift,the low-elevation TTC communication is especially difficult in near-space TTC communications.In this article,two fundamental problems in near-space low-elevation TTC communications are studied：the channel model in near-space low-elevation TTC communications is constructed;and simulations are correspondingly conducted.The parameters of the near-space low-elevation TTC signals are estimated.Simulation results show that the proposed estimation method has good performance and meet the CRB requirements of joint parameter estimation.关键词
