Problems solved by technology
When traditional detection equipment works underwater, it needs an external power supply or communication cable. The former has weak battery life and is difficult to charge, while the latter is costly and has low mobility and flexibility. Due to long-term underwater work, the shell is eroded by seawater and the internal The wear and tear of precision instruments limits the service life of detection equipment and lacks durability; at the same time, the monitoring range of existing underwater detection equipment is still limited to a specific small target area, and the quality of monitoring in noisy or messy environments is still poor. have been greatly affected

Embodiment Construction
[0030] The present invention will be further described below in conjunction with the accompanying drawings.
[0031] 1. Establishment of database
[0032] In order to reduce the difficulty of collecting information, the detected organisms were set in the megafauna community, where the megafauna was defined as organisms with a length > 1.5 cm. Marine organisms will produce certain behavioral responses when stimulated by environmental changes caused by human underwater activities, such as the beluga whale Delphinapterus leucas among marine mammals. Quickly move away from the ship to 80km away, swim out of the water to breathe, change the diving mode, change the population composition, change the vocalization, etc. Another example is that animals are more likely to be disturbed by noise when they are resting than when they are participating in group activities. Dolphins in a resting state tend to avoid ships, dolphins in foraging ignore ships, and dolphins participating in group...

Abstract
The invention relates to bionic detection design, belongs to the field of underwater bionic detection and particularly relates to an underwater target-detection method using organisms as a sensor. According to the underwater target-detection method, underwater detection is conducted by using the organisms as the sensor. With a self-existing ability and as a natural sensor, the bio-sensor is enduring; the bio-sensor is provided with unlimited natural sensor elements capable of self-powering, and a deployment region can be monitored continuously; and organic noises in ocean can be taken as inputsignals, so covering power in time or space is unparalleled.
Description
technical field [0001] The invention relates to bionic detection design and belongs to the field of underwater bionic detection, in particular to an underwater target detection method using living things as sensors. Background technique [0002] In the field of sonar detection at this stage, although the sensor systems for underwater vehicle monitoring have made progress, for the vast ocean environment, there are still large gaps in the coverage of traditional sonar detection in space and time. When traditional detection equipment works underwater, it needs an external power supply or communication cable. The former has weak battery life and is difficult to charge, while the latter is costly and has low mobility and flexibility. Due to long-term underwater work, the shell is eroded by seawater and the internal The wear and tear of precision instruments limits the service life of detection equipment and lacks durability; at the same time, the monitoring range of existing unde...
