ANTENNA RADIATION CHARACTERISTICS WITH PARTIALLY COHERENT ILLUMINATION.
Abstract
The radiation characteristics of a partially coherent illuminated antenna are found for both a circular aperture and a linear antenna. The antenna illumination function is assumed to be Gaussian, and the phase structure function in the plane of the antenna is assumed to be of the form cr nu, with nu = 1, 5/3, and 2. The beam broadening and reduction in gain in dB are found to be of the form Kb alpha, where K and alpha are functions of the antenna illumination and the law of the phase structure function and b is a function of the level of the phase structure function.
