Design and Analysis of a Multiple and Wide Nulling Collaborative Beamforming Scheme in the Domain of 3-Dimensional Wireless Sensor Networks

Table 19

Null width (in degrees) corresponding to null steering at radii 1, 2, 3, and 4 (wavelength normalized). The null width has been measured at the −20 dB power level in the average array factor.
