月球轨道交会对接毫米波雷达系统设计与实现
Design and implementation of millimeter wave radarsystem for lunar orbit rendezvous and docking
摘要
Abstract
According to the characteristics of China's Chang'e-5 unmanned autonomous lunar orbit rendezvous and docking mission,a millimeter-wave rendezvous and docking radar system is designed and implemented,which integrates angle acquisition and tracking measurement with single channel interferometer and rotating mechanism,double one-way pseudo-code ranging and carrier velocity measurement,and TURBO coded spread spectrum communication.The specific composition,working process,measurement and communication methods,design performance and verification of the new radar system are described.The new system has the characteristics of multi-information measurement and two-way communication integration,wide field of view,large distance dynamics,high measurement accuracy,strong anti-multipath capability,small weight and low power consumption.Verified by ground and actual on-orbit applications,the millimeter-wave radar system realizes the full-range high-precision measurement and two-way communication of lunar orbit unmanned rendezvous and docking for the first time.The performance is stable,and the dynamic range of ranging can reach 0.2m to 397km,the accuracy can reach±0.017m,the field of view of angle measurement can reach 360°×130 °,and the accuracy is better than±0.07 °.The system can be applied to the Chang'e-6 mission.关键词
