Description

technical field [0001] The invention relates to a dual-polarization single-channel all-digital radio monitoring and direction-finding mobile station system, belonging to the technical field of array signal digital processing and direction-finding in communication technology. Background technique [0002] With the deepening of radio management work, some low-end user markets need economical and affordable monitoring equipment, so a system represented by the DDF190 system of German R / S company appeared, which uses a single-channel receiver to realize monitoring and direction finding. . However, they are only vertically polarized systems, not dual polarized systems, and are 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 purpose of the present invention is to propose a dual-polarization single-channel all-digital radio monitoring and direct...
