Description

technical field [0001] The invention relates to a dual-polarization multi-channel digital radio monitoring and related interferometer direction-finding fixed station system, belonging to the field of array signal digital processing direction-finding technology in communication technology. Background technique [0002] At present, similar products include the French Esmeralda three-channel system and the German R / S company's DDF05E system. However, they are all only vertically polarized systems, which can only monitor and find vertically polarized signals; there is no dual-polarized system. And expensive. Equipment that can only monitor analog communication signals can no longer meet the needs of digital communication signal monitoring. Contents of the invention [0003] The object of the present invention is to propose a dual-polarization multi-channel digital radio monitoring and related interferometer direction finding system. A three (more) channel digital monitoring...
