Abstract

The invention belongs to the technical field of underwater target detection and positioning, and discloses a shipborne electric field detection and positioning system and method, and the system comprises an electric field sensor, an electric field conditioning and collection system, a computer, an inertial navigation system, and a glass fiber reinforced plastic speed boat. The electric field sensor is fixed to the bottom of the glass fiber reinforced plastic speed boat, and the electric field conditioning and collecting system, the inertial navigation system and the computer are placed on the glass fiber reinforced plastic speed boat. The input end of the electric field conditioning acquisition system is connected with the output end of the electric field sensor, and the computer is respectively in interactive connection with the electric field conditioning acquisition system and the inertial navigation system. The invention provides an electric field measurement platform which can be quickly maneuvered, and can realize the measurement, detection and positioning of a target electric field in water and the positioning of an underwater submarine cable breakpoint and a current leakage point. And the electric field measurement sensor and the glass fiber reinforced plastic yacht body are conformal, so that the maneuverability of the measurement system is greatly improved while electric field interference is reduced.

Description

technical field [0001] The invention belongs to the technical field of underwater target detection and positioning, and in particular relates to a shipborne electric field detection and positioning system and method, which can be used for underwater target detection and positioning, submarine cable breakpoint and underwater current leakage point positioning. Background technique [0002] The prior art shows that the electric field of the underwater target contains rich information. By measuring the electric field of the underwater target, combined with the propagation model and characteristics of the electric field, the detection and positioning of the underwater target can be effectively realized. Electric field measurement and detection and positioning systems have developed rapidly in recent years, and the existing electric field detection and positioning systems are mainly submerged stationary platforms or buoy platforms. [0003] Through the above analysis, the existing...
