An acoustic vector hydrophone measures the scalar acoustic pressure and the vector acoustic particle velocity, thus the DOA can be estimated by single vector hydrophone.
The analytical solutions of stresses, displacement and pore pressure amplitude are derived in frequency domain by introducing two scalar potential functions.
