Aimed at the Difficulties in vector measuring modul Design of vector antenna tuning unit, this paper has designed a short-wave impedance sampling module using Wheatstone bridge, supplying its hardware and software framework so as to research the ...

Due to the differences of scattering areas and directions, the sound scattering influences imposed by a cylindrical baffle on a vector sensor are different when the sensor is installed at different locations. Using the BEM method, the directivities of ...

Focusing in the orthogonal array orientation technology, in this paper, the target Orientation error introduced by the structure of sensor position deviation and the low signal-to-noise ratio (SNR) is analyzed. A simulation experiment aimed at ...

In the free field, making full use of scalar and vector information of acoustic field can bring many advantages for acoustic measurement, but under the conditions of the existence of sound baffle, the sound field should be distorted due to the ...

Passive direction finding is the main capability of AUVs. Methods of direction finding based on single vector are reviewed in this paper. Coherent interference of AUVs itself is very hard for acoustic direction finding system and traditional noise ...

The performance of DOA estimation based on average acoustic intensity degraded badly as the cell spacing of pressure-difference acoustic vector sensor was relatively great, which restricted its potential applications. A new method was proposed to ...

Vector acoustic field of the ocean provides associated information about pressure and particle velocity for acoustic signal processing, of which vector phase, like acoustic intensity and phase difference etc, includes a great deal of information related ...

This paper studies direction finding of electromagnetic energy sources using passive vector sensor arrays whose manifold is only nominally known. The problem of direction finding is studied in the context of an airborne array, thus facilitating the ...
