Problems solved by technology

At present, most of the transmission of radar images of shore-based radar stations with long distances adopts optical cable communication, and most of these radar stations are erected on high mountains, which makes the construction of optical cable laying difficult and expensive. , sometimes just considering these reasons, the site selection of the radar station can only be the next best thing, and choose a relatively good location. Even so, the advantages of large bandwidth, high speed, and low attenuation of optical cable communication are still making it the preferred method of radar image transmission

Abstract

The invention discloses a maritime shore-based radar image transmission system and a transmission method thereof. The system comprises a radar image acquisition server, a GPRS wireless communication module and a radar image network server; the radar image acquisition server acquires, compresses and codes radar images; the GPRS wireless communication module receives the image acquisition instruction sent by the radar image network server, and carries out the wireless communication between the radar image acquisition server and the radar image network server; and the radar image network server carries out radar image acquisition control and display functions. The invention solves the major problem that the transmission of radar images depending on optical cable communication is limited by geographical conditions, consequently, the construction cost of maritime shore-based surveillance radars is greatly reduced, and surveillance on each sea area is more flexible. The application of the GPRS wireless communication module in a maritime shore-based radar station can greatly reduce the difficulty of the construction of the radar station, save the construction cost and achieve the highestcost performance.

Description

technical field [0001] The invention relates to a radar image transmission and display technology, in particular to a maritime shore-based radar image transmission system and a transmission method thereof. Background technique [0002] The site selection and construction of maritime regulatory radar has always been a headache for the maritime management department. It not only needs to consider many technical problems of radar radiation coverage, but also selects the site according to the natural conditions such as topography. Due to the laying of communication optical cables is one of the important factors, and sometimes directly negates the location of an ideal radar station because of the laying of communication optical cables. At present, most of the transmission of radar images of shore-based radar stations with long distances adopts optical cable communication, and most of these radar stations are erected on high mountains, which makes the construction of optical cable...
