FORMATION OF NULLS IN VECTOR BEAM PATTERNS OF MONOPULSE ARRAYS OF RECTANGULAR WAVEGUIDES BY CORRECTING CURRENTS IN SOME ARRAY ELEMENTS

摘要

In this paper, we consider a method for null synthesis in the vector sum and difference beam patterns of a monopulse array of rectangular waveguides. The synthesis of nulls is reached due to variation of complex currents in some elements. The proposed method eliminates shifts of the primary maximum and the nulls of the sum and difference beam patterns, respectively, of a monopulse array. Numerical studies confirming the efficiency of the proposed method are described.
