Abstract

The invention relates to a nine-channel space spectrum super-resolution estimation monitoring and direction-finding mobile station system, which comprises a small double-cone omnidirectional monitoring antenna, a nine-unit direction-finding antenna, an amplifier, a monopole monitoring antenna, a nine-channel signal switching module, a filter combiner, am amplifier module, a nine-channel receiver, a monitoring and direction-finding controller, a DSP (Digital Signal Processor) processing module, an imbedded industrial computer, a GPS (Global Positioning System) antenna, a GPS module, a 3G (3rd Generation) antenna, a 3G router, a power supply module, a remote control unit, an exchanger, and the like. The system has the following advantages: the system achieves remote and automatic monitoring and direction-finding of radio signals; an imbedded computer system is integrally arranged so that the structure is compact and light; a direction-dinging assembly solves the coupling problem between the antenna arrays and prevents coupling and phase between unit antennas from being blurred; the structure is compact and light, and the spanning maintenance is convenient; the grid connection is flexible, and can support different wired / wireless network data transmissions; moreover, collection, compression coding, automatic task monitoring, statistic analysis and abnormal state alarm of wireless signals are realized.

Description

technical field

[0001] The invention relates to a nine-channel spatial spectrum estimation super-resolution monitoring direction finding mobile station system, which belongs to the technical field of radio monitoring. Background technique

[0002] The construction of radio monitoring and direction-finding fixed stations needs to occupy a large amount of land, and the range of monitoring and direction-finding is relatively limited, so some mobile monitoring station systems are needed to supplement the entire radio monitoring and direction-finding network. In addition, in practice, we found that multi-signal simultaneous monitoring and direction finding pose new challenges to radio monitoring and direction finding. For example, in radio management, we often encounter the situation that the disturbed user communication is not allowed to be interrupted (such as the communication navigation frequency of the airport, public communication), and the use of multi-base station transmi...
