Direction of Arrival Filters for Improved Aberration Estimation
Ultrasonic Imaging, 2008Successful adaptive imaging requires accurate measurements of the aberration profile across the array surface. Two-dimensional spatial filters are used to obtain more accurate estimates of aberrating layers by suppressing wavefronts emanating from off-axis scatterers.

Estimation of Direction of Arrival Algorithms
2013MUSIC and ESPRIT algorithms are two of the most widely known and used signal source estimation techniques. This study aims at the comparison of the performances of these two techniques. In this study, the signals coming toward uniform linear antenna arrays are estimated using MUSIC and ESPRIT algorithms.

Seasonal Variations in Direction of Arrival
1969It is obvious from fig. 8.3 that the scatter of the received bearing directions is very large, especially during the time periods 0300 to 0900 and 1500 to 2100 GMT. Nevertheless, it is possible that some limits to this variation could be indicated by an investigation of the average behaviour over a long period.

Deep Binaural Direction of Arrival Estimation
The objective of binaural direction of arrival (DoA) estimation is to find the DoA of a sound source by measuring the sound field with a binaural array. This field increasingly applies deep learning to this task, particularly convolutional neural networks which are trained on relatively raw representations of the binaural audio.openaire +1 more source
