The categorization to one of the two cases depends on the aperture of the array and the distance between the source and receiver. As illustrated in Fig. 1, the wavefront originating from a source in the far-field can be described as a plane wave. The angle of incidence is identical for...
The aperture of an isotropic antenna is Gain is relative to isotropic radiation, making the effective aperture of an antenna Pulling these three terms together, we can see that gain can be considered a function of angle that defines a radiation pattern and accounts for efficiency (or losses) ...
Introductory chapters are provided on basic aperture and array theory, including the calculation of the radiation pattern, beam dimensions, sidelobes and aperture taper, and periodic array synthesis. Aperiodic arrays are briefly considered, while chief attention is given to theory of the random array,...

where m and d denote the number of microphones and the spacing between neighboring sensors, respectively. l = m d is the array aperture. therefore, the spatial discrimination capability depends on the array aperture size, i.e., discrimination improves with a larger aperture size [ 13 ]. if ...
