Abstract

The invention relates to a generating and receiving system applied to an underwater vehicle and an implementation method thereof. The generating and receiving system comprises a generating device anda receiving device, wherein the generating device pushes adjacent seawater to generate wake flow, and stirs sodium ions and chloride ions in seawater to induce a Debye magnetic field; the receiving device comprises a control processor, a laser, a photoelectric detector and a probe mechanism, wherein the probe mechanism is arranged in a Debye magnetic field; the probe mechanism comprises two non-magnetic optical fiber collimators, a temperature control mechanism and an atomic gas chamber; the receiving device adopts a coherent population capturing method in a parallel double-linear polarized light mode, Debye magnetic field information is calculated from space collimated light generated by the probe mechanism, and accurate measurement of the Debye magnetic field information is realized; according to the invention, the resolution ratio of the receiving device in the generating and receiving system can reach 0.001 nT, the sampling rate is larger than 10 Hz, the detection requirement can be met, and the generating and receiving system has the advantages of being high in magnetic field detection sensitivity, simple in structure, easy to achieve in an engineering mode and the like.

Description

technical field [0001] The invention relates to a generating and receiving system applied to an underwater vehicle and a realization method thereof, which are used for detecting and locating a Debye magnetic field of a large underwater vehicle such as a submarine, and belong to the technical field of atomic magnetometers. Background technique [0002] As traditional underwater vehicles, such as submarines, remanence control technology becomes more and more advanced, it becomes more and more difficult to detect and locate submarines through traditional magnetic anomaly measurement technology. Since the Debye magnetic field induced by the wake of the underwater vehicle has the characteristics of being like a shadow, it cannot be eliminated within a certain period of time and within a certain distance. Therefore, the Debye magnetic field receiver with certain characteristics can be used to realize the detection and positioning of the target of the underwater vehicle. . [0003...
