Abstract
The dyadic sensors are of current interest in a number of applications. After the output correlation matrix of the dyadic sensor in the isotropic noise field is derived, the processing gains of conventional beamformer (CBF) and optimum gain beamformer (OGBF) based on single dyadic sensor are duduced. The results of several examples indicate that the dyadic sensor can obtain much more bigger processing gain with a small package, its optimum gain can reach 9.5 dB and its conventional processing gain is about 5.7 dB.
