Ship-borne radar

Abstract

The invention discloses a ship-borne radar which comprises a transceiving antenna, a rotating hinge, a high-frequency waveguide transmission line, a transmitter, a high-frequency switching device, a high-frequency receiver, a signal shaper, a low-frequency receiver, a secondary data processing device and a ship-borne radar control unit. The output end of the transmitter is connected to the input end of the transceiving antenna, and signals received by the transceiving antenna are transmitted to the low-frequency receiver. Intermediate-frequency linear frequency modulation signals are generated in the low-frequency receiver, enter the signal shaper from an output end, pass through the switching device, the waveguide transmission line and the rotating hinge from the output end of the transmitter and are transmitted to the antenna to be radiated out. Echo signals received by the transceiving antenna reach the input end of the high-frequency receiver, high-frequency receiver signals are transmitted to the input end of the low-frequency receiver and are transmitted to the second data processing device from the low-frequency receiver, then the signals are transmitted to the ship-borne radar control unit, and storage batteries are connected with the ship-borne radar control unit to supply power to the ship-borne radar control unit. The ship-borne radar is high in universality, convenient to maintain and little in influence of external interference.

Description

technical field [0001] The invention relates to the field of shipboard radio communication, in particular to a shipboard radar. Background technique [0002] At present, radar technology is used in ships, aircraft or vehicles. On the one hand, the radar devices traditionally used on ships are relatively large in size, and the entire life cycle of ship-borne radar units is relatively low, so maintenance and replacement are very frequent; on the other hand, ordinary The commonality of the shipborne radar is poor. The external interfaces of different units in the same type of radar and the same functional unit in different types of radars are different. As a result, each different unit has a dedicated display and control device. The amount of equipment is large and the maintainability is poor. , and will be affected by sea reflection echo, interference and environmental noise on radar performance. Contents of the invention [0003] Aiming at the deficiencies of the pr...
