However,in shallow water,because the arrival signals of the vertical linear array are not plane waves,the spatial gain needs to be estimated properly.

Firstly,the elementary principle of underwater target depth measure is studied,which is supported by underwater acoustic detection system of vertical linear array and is conducted in deep sea.

Using perpendicular arrays,one class of Cartesian authentication code is constructed and its size parameters are computed.

In this paper,by using perpendicular arrays,the authors construct one class of non-Cartesian authentication code,and compute its size parameters.

The principle of passive localization based on vertical linear array and observability analysis

A brief introduction of vertical linear array is presented in this paper.

In this paper the measurement of sound velocity and thickness of seabed sediment are introduced using the vertical linear array which is concerned with sound refraction and reflection.

The principle and realization of digital multi-beamforming in linear arrays based on DSP;

The device of vertical wall array was demonstrated,and the corresponding technological process was presented.

A new direct conversion device of vertical wall array for Radioisotope Micro Battery (RMB) is designed to enlarge the surface area.
