Description

technical field [0001] The invention relates to a satellite test system, in particular to a dynamic beam tracking test device and method for a satellite-borne digital multi-beam receiving antenna. Background technique [0002] With the continuous development of new technologies such as Adaptive Digital Beam Forming (DBF) in the field of satellite communications, many satellites now use satellite-borne digital multi-beam antennas. The digital multi-beam antenna can flexibly control the direction function of the antenna array by weighting the received data of the antenna array elements to form various beamforming, which can not only effectively suppress interference, but also improve the signal-to-noise ratio of useful signals. Most adaptive digital beamforming (DBF) algorithms are complex and have a large amount of calculation, which puts forward higher requirements for the accurate testing of spaceborne digital multi-beam antennas. Especially for satellite-borne digital mul...
