Embodiment Construction

[0043]First of all, it should be explained that the present invention not only provides a digital marine radar system based on optical fiber communication, but also provides a signal transmission method of the digital marine radar system based on optical fiber communication. The marine digital radar system based on optical fiber communication provided by the present invention constructs a two-way signal transmission channel between radar transceiver functional equipment and radar signal display equipment by using optical fiber. Among them, the signal processing function is added to the radar transceiver function equipment, and the radar analog signal is processed into a digital signal, and the radar digital signal is sent to the radar signal display device in the form of optical fiber communication, so as to display the image or video information of the radar. At the same time, the radar transceiver function device detects the control signal sent by the radar signal display dev...

Abstract

The invention discloses a ship radar system based on optical fiber communication, and a signal transmission method thereof. The radar system comprises radar transceiver function equipment, radar signal display equipment, and distributed-type power supply equipment. The radar transceiver function equipment transmits a microwave signal for radar scanning through a radar antenna, and receives a radar echo signal. The radar signal display equipment is used for displaying radar video information, and the bidirectional signal transmission between the radar transceiver function equipment and the radar signal display equipment is achieved in a mode of double-fiber communication. The signal transmission method comprises the steps: 1, obtaining a radar digital signal through the radar transceiver function equipment, transmitting the radar digital signal to the radar signal display equipment; 2, setting a control signal through the radar signal display equipment, and enabling the control signal to be transmitted to the radar transceiver function equipment. According to the invention, the wiring is easy, the anti-interference capability is strong, and the image quality is high.

Description

technical field [0001] The invention relates to a digital radar system, in particular to a digital radar system based on optical fiber communication, and also relates to a signal transmission method of the digital radar system based on optical fiber communication. Background technique [0002] my country has a long coastline and numerous inland rivers and lakes, which correspond to a huge fleet of transport fleets, ocean-going ships, fishing boats, military ships and other ships. In the operation of various ships, radar and peripheral equipment used in conjunction with radar are often required equipment, which provides an important guarantee for the crew to keep abreast of the surrounding environment of the ship and improve navigation safety. The current marine digital radar mainly uses copper cables to transmit video information, and the synchronization signals between various peripheral devices and the radar are also transmitted in the form of cables. Since the cable for ...
