Shipborne maritime wireless communication monitoring system

Abstract

The invention provides a shipborne overwater wireless communication monitoring system, which comprises a shipborne correlation interferometer direction-finding antenna array, an electrical rotation unit, an RF amplifier module, a card direction finding receiver, a direction-finding control processing module, an embedded computer system and a power supply module. The system has the advantages that an integrated design, the intermediate frequency signal technique and the modularized combination are adopted; the built-in embedded computer system is adopted, so that the structure is compact and portable; the portable passive correlation interferometer direction-finding antenna is adopted to solve the mutual coupling between the antenna array cells to eliminate the coupling and the phase ambiguity between element antennae; the multifunctional amplifier is adopted and automatically switched to enlarge the dynamic application range of the received signal; the card double-channel monitoring direction-finding receiver is equipped, so as to carry out the monitoring and the direction-finding by a sharing time, and switched into the radio monitoring without the need of the direction-finding; and the compensation algorithm software is corrected and combined with an electronic nautical chart and a ship recognition system to meet the requirements for the overwater / offshore monitoring.

Description

technical field [0001] The invention relates to a ship-borne wireless communication monitoring system on water, and belongs to the technical field of array signal digital processing and direction finding in communication technology. Background technique [0002] Maritime radio communication frequency is a precious natural resource. Establishing a reasonable, orderly, and interference-free radio communication environment is the basis for maritime communication, especially distress safety communication. The radio communication order must be managed scientifically and orderly. In order to maintain the order of radio communication on the water, establish and maintain a good working environment for safe radio communication on the water, monitor the frequency bands of safe communication in distress on the water, and check and filter key interference sources, it is necessary to develop special shipborne water radio for the maritime department. Communication monitoring system. Co...
