Abstract

The invention discloses a multi-array-element single-channel interference angle measurement device which comprises an antenna array. The antenna array comprises a plurality of receiving antennas, an angle measurement receiving channel and a processing unit, the receiving antennas form azimuth baselines and pitch baselines respectively, the angle measurement receiving channel converts radio-frequency signals output by the receiving antennas in the antenna array into intermediate frequency signals and outputs the intermediate frequency signals to the processing unit, and the processing unit determines phase differences among the receiving antennas at the same receiving time in the antenna array according to sampling signals of the intermediate frequency signals, obtains azimuth angles of the azimuth baselines and pitch angles of the pitch baselines respectively and outputs the azimuth angles and the pitch angles. According to the multi-array-element single channel interference angle measurement device, single-channel receiving and two-dimensional angle measurement of the antenna array are achieved.

Description

technical field

[0001] The invention relates to a multi-element single-channel interference angle measuring device. Background technique

[0002] The main task of the third phase of the lunar exploration project is to obtain lunar soil from the moon and return it to the earth. Among them, the ascender in the probe will rendezvous and dock with the orbiter after returning to the lunar orbit from the moon. Lunar orbital rendezvous and docking microwave radar is an important device for relative measurement and communication in the middle and long distances of docking. The lunar orbit rendezvous and docking microwave radar measures the distance between the ascender and the orbiter, and the azimuth and elevation angles of the ascender relative to the orbiter by establishing a two-way link between the orbiter and the ascender. Space position information such as the distance, azimuth, and pitch angle of the ascender relative to the orbiter is the basis for implementing space rend...
