  3. Abstract:
  4. Fast, accurate and efficient sensing is of important aspects in cognitive radio technology. We propose a simple, practical design for two-dimensional sensing in spectral and spatial domain. In fact detection and localization of signal are done in a wide band elliptical array. Two sets of phase differences help to fast calculation of frequency and angle of arrival. We study the constraints, advantages and accuracy of the method. ©2009 IEEE
