摘要
Abstract
The visible period of reentry capsule is short after getting out of the blackout area,which requires the fast target capture capability of the spacecraft TT&C system.To address the challenge,a detection algorithm based on digital multi-beam is proposed.The different beams formed by the beam former detect the TT&C signals simultaneously in the corresponding regions. When the signals are detected,the multiple beams validate the results simultaneously, and the multi-channel signals are combined into a set of data for correlation detection.A computational simulation is further carried out to verify the detection probability and false alarm probability performance.The results show that the proposed method can shorten the detection time and improve the detection probability obviously with lower cost,meeting the requirements for fast capture of reentry capsule.关键词
