Embodiment Construction

[0090] The technical solution of the present invention will be further elaborated below in conjunction with the accompanying drawings of the description.

[0091] like figure 1 and figure 2 Shown, a kind of sea ship location identification method based on radio signal processing is characterized in that: comprises the following steps:

[0092] Use radio direction finding equipment to scan the 20MHz covering the sea area ～ 3000MHz signal; the radio direction-finding equipment will scan and find the direction of the radio signal that continues to appear, and the control center will collect the scanning data of several radio direction-finding devices for analysis, and perform preliminary direction-finding positioning through the multi-station network direction-finding function;

[0093] Collect ship MMSI signals, latitude and longitude, and ship registration information through the AIS system, and integrate the positioning data of the radio direction finding equipment and the ...

Abstract

The invention discloses a marine ship positioning and recognizing method based on radio signal processing and relates to the technical field of marine radio. Radio direction-finding and an AIS are combined together to position ship condition and recognition information, an interactive multi-model is applied to calculate and predict ship sailing direction and ship position, and a ship can be prewarned and called when it is predicted that the ship position may intrude a warning area or may be on a typhoon path.

Description

technical field [0001] The present invention relates to the technical field of marine radio, and more specifically relates to a method for positioning and identifying marine ships based on radio signal processing. Background technique [0002] For maritime navigation, maritime radio station communication is an important channel for maritime operation information communication and the lifeline of maritime safety, and ship radio station is an indispensable tool for maritime communication. Maritime radio station monitoring is based on the radio direction finding and positioning technology and radio monitoring technology provided by the maritime radio management and detection system. Radio direction finding technology includes radio direction finding technology and radio positioning technology. [0003] Radio direction finding is accomplished by radio equipment that measures electromagnetic waves in space. It is the process of using radio measuring equipment to determine the a...
