Underwater multi-physical field composite detection system and detection array optimization method

Abstract

The invention discloses an underwater multi-physical field composite detection system and a detection array optimization method. An objective function is established through a flow field simulation analysis algorithm model, a flow field detection sensor array is optimized, and flow field information around an underwater vehicle is detected and captured. An electric field detection electrode array is optimally designed through information standard deviation calculation, electromagnetic field simulation analysis and an orthogonal experiment method, underwater target objects are identified and positioned, the positioning precision and the identification accuracy are improved, and the underwater detection range is widened. Two propagation media of flow field detection and electric field detection are adopted as detection modes, the interference of turbid water on detection can be effectively overcome, the defect that the precision is low when a traditional manual lateral line sensor and an electric receptor which singly measure water pressure or electric field changes are used for measuring a moving target is overcome, and acoustic near-field detection blind areas are made up. Through the combination of flow field detection and electric field detection, the underwater detection range is expanded, and the accuracy of underwater target identification and positioning is improved.

Description

technical field [0001] The invention relates to the technical field of underwater detection, in particular to an underwater multi-physical field composite detection system and a detection array optimization method. Background technique [0002] The detection and recognition of underwater target objects has become a research hotspot in the field of modern national defense and ocean engineering. According to different detection methods, there are currently two traditional underwater detection methods, namely underwater acoustic detection and underwater optical detection. The basic principle of underwater acoustic detection is to transmit ultrasonic waves through acoustic equipment, and then receive the scattered echoes generated by the sound waves on the surface of objects; optical detection usually uses optical imaging equipment to directly image underwater targets. However, both methods are prone to reverberation interference and the accuracy is not high, and the detection ...
