Multifunctional radar ship illegal fishing-based behavior discrimination method

Abstract

The present invention discloses a multifunctional radar ship illegal fishing-based behavior discrimination method. The multifunctional radar ship illegal fishing-based behavior discrimination method comprises the steps of firstly presetting the illegal fishing alarm rules and presetting a supervision area set S; secondly, real-timely processing the radar scanning echo data to obtain the information of the ships, such as the positions, the sizes, the motion state, etc., in the ranges of the preset supervision areas; then according to the preset illegal fishing alarm rules, discriminating whether a target ship is illegal, and outputting an alarm level; and finally, according to the alarm level, triggering different types of alarms. According to the present invention, based on the actual law enforcement experiences, by combining a radar detection technology, and by the illegal fishing discrimination rules, the illegal ships are identified automatically, the water area supervision capability based on a multifunctional radar system is improved effectively, the dynamic states of the water ships are grasped timely and effectively, the timely and effective ship illegal information is provided for the law enforcement officials and the supervision departments, the law enforcement supervision efficiency is improved, the law enforcement cost is reduced, and the water illegal fishing behaviors are fought effectively.

Description

technical field [0001] The invention relates to the technical field of marine fishery illegal fishing supervision, in particular to a method for judging illegal fishing behavior of ships based on multifunctional radar. Background technique [0002] China is a large oceanic country, with more than 3 million square kilometers of oceanic territory, rich in fishery resources, providing humans with a large amount of high-quality food, and at the same time bringing huge economic benefits; however, in recent years, as illegal fishing has become increasingly rampant, Illegal fishing methods are increasingly modernized, resulting in an imbalance in the structure of fishery resources, destroying the ecological environment of water areas, challenging the sustainable development of my country's fishery resources, and seriously affecting the process of my country's ecological civilization construction. [0003] At present, traditional fishery law enforcement relies on reports from the mas...

Problems solved by technology

[0005] The technical problem to be solved in the present invention is to provide a method for discriminating illegal fishing based on multifunctional radar vessels for the deficiencies of the above-mentioned prior art. The method for discriminating illegal fishing based on multifunctional radar vessels is based on actual law enforcement experience. Combined with multi-functional radar detection technology, it can automatically determine whether the target has illegal fishing behavior, and then issue relevant alarm information to provide decision-making basis for law enforcement personnel and management departments, thereby solving the difficult problem of fishery supervision
