AI Technical Summary

Problems solved by technology

The construction cost of the magnetic field shielding room is extremely high, and it is related to the volume of the space. The larger the volume, the higher the cost
The magnetic field strength is a vector parameter, not only has the size, but also the directionality, which determines that the measurement space of the magnetic field cannot be too small, and the cost will increase accordingly

Abstract

The invention relates to the fields of an underwater acoustic positioning technology, an electromagnetic radiation technology, an electromagnetic receiving technology, an electromagnetic vector characteristic measurement technology, a signal processing technology and the like, and provides an electromagnetic vector parameter measurement method and system for a deepwater low-electromagnetic interference environment based on underwater acoustic three-dimensional space positioning. A movable deck catamaran shipborne hanging mode is adopted, and an electromagnetic radiation device and an electromagnetic receiving device are hung at the depth of 50m or above underwater in a flexible connection mode. By moving the position of the movable deck, changing the relative position and the lifting depthof a lifting point and a ship board, three-dimensional coordinate distribution is achieved; a natural electromagnetic barrier formed by deep water is utilized to obtain an ultralow background noise electromagnetic environment; according to the invention, the large cost for constructing a magnetic field shielding chamber is saved, the relative distance and angle between the transmitting and receiving electromagnetic arrays are obtained by adopting underwater acoustic space precise positioning, the magnetic field is measured by using a three-component electromagnetic receiving sensor, and magnetic field vector characteristic parameter calibration in an ultralow background electromagnetic noise environment is realized under the condition of low cost.

Description

technical field [0001] The invention relates to the technical field of electromagnetic vector parameter measurement, in particular to an electromagnetic vector parameter measurement system and method for a deep-water low electromagnetic interference environment. Background technique [0002] Magnetic field measurement is the technical basis for applications such as electromagnetic radiators, electromagnetic connectors, and space magnetic field cancellation. Without high-precision, scientific measurement techniques and methods, it is impossible to accurately measure magnetic field parameters.
