摘要:
针对月球轨道自主交会对接任务特点,设计一种测距、测速、测角、通信一体化的先进交会对接微波雷达系统。该雷达系统采用高速伪码延时测距、双程相干多普勒测速及相位干涉仪测角体制完成测量功能,采用QPSK调制与RS编码完成扩频通信功能,具有测量通信一体化、测量参数全、测量精度高、小型化低功耗、使用方便可靠等特点。经实际在轨验证,该雷达系统首次实现了月球轨道无人交会对接全程高精度多元信息测量及可靠双向通信,综合技术达到国际先进水平。

Abstract:
Aiming at the characteristics of the lunar orbit autonomous rendezvous and docking task,an advanced rendezvous and docking microwave radar system integrating ranging, velocity measurement, angle measurement and communication is designed.The radar adopts high-speed PN code delay ranging, round-trip Doppler frequency velocity measurement and Interferometric angle measurement system to complete the measurement function, and uses QPSK modulation and RS coding to complete the spectrum communication function. The system has the characteristics of integration of measurement and communication, complete measurement parameters, high measurement accuracy, miniaturization, low-power consumption, convenient and reliable use, etc. Through the actual orbit verification, the radar system has realized the high-precision multiinformation measurement and reliable two-way communications in the whole course of unmanned rendezvous and docking in lunar orbit for the first time, and the comprehensive technology has reached the international advanced level.
