New Future Spacecraft Navigation Tool: Interferometry Technology Based on Antenna Array

摘要

According to TT&C challenges such as remote range distance, limited transmitting power, weak station received signal in deep space exploration, a new navigation tool of deep-space spacecraft called Interferometry Technology Based on Antenna Array is proposed in this paper. It utilizes the capability of signal receiving and processing in antenna array technology, and utilizes the capability of high accuracy measuring in interferometry technology, and combines the two technologies for high accuracy measuring in low SNR condition in deep space exploration missions. The principle of interferometry technology based on antenna array is briefly analyzed, and several key research contents in signal processing of interferometry based on antenna array are discussed. It shows that the method of interferometry based on antenna array will have important application in future deep space exploration measuring missions.
