Potentially Achievable Levels of Lateral Radiation of an Equal-Amplitude Nonuniformly-Filled Array
2021
The task of minimizing the lateral radiation level of a linear uniform amplitude array with a uniform amplitude distribution using the space-tapered allocation of its elements is considered. It is demonstrated that the use of the evolutionary method of parametric optimization makes it possible to find the coordinates of isotropic elements of the array providing the minimum values of the maximum level of the side lobes in the radiation pattern. The search for the different values of the number of elements as well as for the length of the array is performed. The dependences of the potentially attainable side lobe level upon the number of array elements are obtained for the different values of the array sparseness.
