Problems solved by technology
The traditional measurement method mainly uses the acoustic method to estimate the deep-sea vertical formation, which usually needs to actively transmit signals in multiple directions, and cannot achieve real-time estimation
The deep-sea vertical formation estimation method based solely on the azimuth sensor and the inclination sensor, usually due to the installation error of the inclination sensor, the estimation accuracy of the deep-sea vertical formation is greatly reduced
However, the pure use of depth sensors can only estimate the two-dimensional formation of the deep-sea vertical array, but cannot estimate the three-dimensional formation of the deep-sea vertical array, which is difficult to apply in the actual three-dimensional ocean environment

Description
technical field [0001] The invention belongs to the technical field of deep sea acoustic physical measurement, in particular to a deep sea vertical array measurement device and a measurement method. Background technique [0002] The accurate estimation of deep-sea vertical array formation is an important prerequisite for the application of sonar vertical array signal processing technology. The deep-sea vertical formation is usually affected by ocean currents and has different formation structures in water at different times. The traditional measurement method is mainly based on the deep-sea vertical formation estimation method using the acoustic method, which usually needs to actively transmit signals in multiple directions, and cannot achieve real-time estimation. The deep-sea vertical formation estimation method based solely on the azimuth sensor and the inclination sensor, usually due to the installation error of the inclination sensor, the estimation accuracy of the dee...
