Optimization of an antenna radiation pattern in conditions of spatial noise
Abstract
The paper examines the problem of synthesizing an antenna radiation pattern in the presence of spatial noise zones limited, for example, by fixed angular directions. If the noise directions are characterized by discrete angles the values of which cannot be determined precisely, the noise should be assumed to be distributed in a limited angular sector, which assures a more reliable suppression. An example is considered which makes it possible to calculate the dependence of the pattern on the initial conditions. In the example considered (L/lambda = 80 and phi = 10 deg, where lambda is the wavelength and phi is the angular direction of the signal) the pattern is determined under the assumption that the noise zone is limited by angles theta1 = 11 deg and theta2 = 13 deg, i.e., that the noise is distributed in the 1113 deg interval. Results show that the pattern synthesis can be carried out on the basis of numerical optimization techniques.
