Abstract

The invention discloses an experimental system and method for detecting frequency targets of underwater moving submersibles; The mobile submersible (20) consists of a base station of the survey ship to control the movement attitude and data acquisition and processing of the submersible (501), submersible (502), and submersible (503) through wireless communication. The present invention uses impedance analysis based The theoretical experimental method adopts submersibles (501), submersibles (502), and submersibles (503) as carriers for data collection, and detects and recognizes positions of underwater mobile submersible frequency targets of known frequencies. The experimental device has the characteristics of simple structure, high detection efficiency and long detection distance. The invention can not only detect the underwater moving target with known frequency, but also can identify the underwater moving target.

Description

technical field [0001] The invention relates to an experimental system and method for frequency target detection of an underwater mobile submersible, in particular to the technical field of frequency target detection for a mobile submersible. Background technique [0002] There are two main methods for detecting underwater submarines: anti-submarine patrol aircraft and anti-submarine surface ships. [0003] Anti-submarine patrol aircraft use sonobuoys, magnetic anomaly detectors, and drop-type sonars to detect underwater submarines. Among them, sonobuoy is a main submarine search equipment commonly used by modern anti-submarine aircraft. It is generally used in sea areas known to have submarine activities, and when it is necessary to search a large area in a short period of time; or it is hoped to block within a certain period of time. Channels that enemy submarines may pass through; or used when anti-submarine patrols are used for important targets. The magnetic anomaly d...
