Maritime peril target search system and method based on marine radar

Abstract

The invention provides a maritime peril target search system and method based on marine radar. The system comprises a signal transceiver, a radar control unit, a search and rescue processing unit and an electronic chart unit; the signal transceiver is used for transmitting and receiving electromagnetic waves and echo signals of the electromagnetic waves; the electronic chart unit is used for providing sea surface geographic coordinates; the search and rescue processing unit is used for converting the electromagnetic spectrum echo signals received by the signal transceiver into digital signals, the digital signals are subjected to filter processing, random noise and wave disturbance from the surroundings are removed, data obtained after filtering is subjected to image processing, and the processed image is subjected to feature extraction, target recognition and classification. Through the maritime peril target search system and method, the ability in searching and rescuing peril targets on the sea surface of deep and far sea can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of maritime target search, and in particular to a marine radar-based search system and method for maritime distress targets. Background technique [0002] With the continuous deepening of my country's development of marine resources in the South China Sea, the number of marine engineering and offshore operations is increasing, and the safety of marine operators and the search and rescue operations of special equipment have become increasingly prominent. In the long sea search after Malaysia Airlines MH370 lost contact, although my country has dispatched many of the most advanced domestic search and rescue ships, it has also exposed problems such as the lack of my country's sea and deep sea search equipment, which restricts the effectiveness of my country's deep sea search and rescue capabilities. play. At present, maritime search and rescue mainly adopts visual search and rescue methods...

AI Technical Summary

Problems solved by technology

[0004] 1. At present, most of the search and rescue methods are artificial visual recognition targets, the search and rescue speed is slow, and the targets are easy to lose

[0005] 2. The ship-borne search equipment is expensive and needs to be erected separately. When used, it is often affected by the surrounding environment. In case of bad weather and sea conditions, some equipment will not work normally

Moreover, the shipborne search equipment has a single use and purpose, and is only suitable for target finding

[0006] 3. The existing radar equipment on board is mainly used for ship navigation. Small targets in distress at sea are easily regarded as sea clutter or interference signals and are rejected by marine radar, so the detection ability of small targets is not good.
