Abstract中国深空网的建立用以支持我国正在实施的探月工程及后续火星、小行星、木星等探测任务。为验证中国深空网的跟踪测量能力,并获取行星无线电测量数据,基于中国深空站开展了对木星在轨探测器"朱诺号"(Juno)的跟踪测量试验与数据处理分析。在分析各种观测约束条件的基础上,首次实现了中国深空站在地—木距离上的深空探测器开环跟踪测量,通过VLBI数据采集记录终端原始探测器信号,经信号处理提取"朱诺号"探测器的主载波频率。采用傅里叶变换(Fast Fourier Transform,FFT)、线性调频Z变化及信号本地重构相关的联合信号处理方法,"朱诺号"探测器主载波频率提取噪声水平在10μHz水平,有效验证了深空开环测量技术,为后续我国深空探测任务积累了有益经验。
Other AbstractThe construction of China’s deep space network supports China’s deep space missions, such as explorations of Lunar, Mars, Small planets, Jupiter, and etc. To validate China’s deep space network performance and obtain the radio measurement raw data, dozens of radio open loop measurement experiments of Juno which is one of Jupiter’s probe on orbit were accomplished. These open loop measurement experiments are the first time conducted by the China’s deep space stations tracking a in-orbit probe in Earth-Jupiter distance. VLBI terminate sampling and recording facilities were utilized to record Juno’s raw carrier signal, which was processed to extract Doppler frequency between Juno and the deep space station. In this paper, the combining method of Fast Fourier transform, Chirp Z transform and signal local reconstruction was utilized to obtain Juno’s Doppler frequency. The results show that Juno’s open loop Doppler frequency is at the level of 10 μHz, which effectively validated the method of deep space open loop measurement and provide valuable reference for China’s future deep space missions.
