Abstract

The results of numerical simulation of an antenna array radiation pattern in impulse mode by the method of sampling phased array signal processing are represented in this paper. The studies of array parameters impact (the number of elements and the distance between them) on its penetrometer characteristics are discussed. It is established that the change of the distance among array elements leads to narrowing of the main lobe of the radiation pattern as well as to shifting of the side lobes nearer to the main one. Meanwhile, the increase in the number of elements in the array leads to narrowing of the main lobe and decreasing of the side lobes level.
