Signal-To-Noise Gain of an Idealized Array Pattern as a Function of Major Lobe Width.
Abstract
An idealized receiving pattern is hypothesized. For this pattern, the directivity ratio is fixed to a constant value. Thus the minor lobe is decreased when the major lobe is broadened. The signal-to-noise gain for isotropic noise does not change as the major lobe is broadened. However, the signal-to-noise gain does change if the noise is directional surface noise. For the conditions examined, increasing the width of the major lobe results in an increase of signal-to-noise ratio. (Author)
