Abstract

The invention discloses a ship radar system on the basis of network transmission. The ship radar system comprises a host unit, a receiving and transmitting unit and an antenna unit. The host unit is mounted in a cab and is used for controlling radar; the receiving and transmitting unit is mounted at a high location outside a ship, is electrically connected with the host unit and is used for carrying out data interaction with the host unit; the antenna unit is mounted at a high location outside the ship, is electrically connected with the receiving and transmitting unit and is used for transmitting electromagnetic waves and receiving echo signals from target objects. The ship radar system has the advantages that the requirements of the host unit on the computation speeds of devices can be lowered, accordingly, pictures are smooth, and echo picture details are easy to present; software and hardware platforms can be provided to multi-radar networked management by the aid of network transmission.

Description

technical field [0001] The invention belongs to the technical field of marine radar, in particular to a marine radar system based on network transmission. Background technique [0002] Marine radar works in the microwave band, mainly X-band or S-band, and the frequency is very high. The power microwave emitted from the antenna returns to the receiving antenna after being reflected by the measured target, and then the useful target signal is picked up through tuning and mixing. The echo signal is processed by the back end to form a graphic displayed to the user, or other signal forms required by the user. [0003] Usually, there is a division of labor between the radar transceiver and the host display. The transceiver receives the power-on and other control signals of the host display, and is mainly responsible for forming high-power microwave transmission, antenna scanning, receiving echoes and processing them into video signals to send to the host display. The host display...
