Description

technical field [0001] The invention relates to a dual-mode antenna tracking system, in particular to a dual-mode antenna tracking system based on spread spectrum and digital guidance. Background technique [0002] Directional antenna tracking technology has always been one of the key technologies in radar, navigation, and air-ground communication data link systems. The traditional fixed-beam (non-DBF digital beamforming) radar antenna directional tracking technology often uses chirp signals combined with pulse compression systems. By generating chirp signals of different types and parameters, the "pulse pressure ratio" is adjusted to improve the instantaneous signal-to-noise ratio. To achieve the purpose of anti-jamming antenna tracking. This system can be considered as an implementation of the spread spectrum technology in the analog domain. However, traditional directional antenna tracking techniques often do not have data link communication capabilities unless addition...
