Amplitude synthesis of radiation pattern with the lowest level of the first side lobe and controlled reduction of other side lobes for antenna arrays

Authors: Layko K. A., Filimonova Yu. O.

Annotation: The synthesis of amplitude distribution for the Array antennas by the method of superposition which differs from other well-known methods, such as Fourier integral method, Partial diagram method or Dolph-Chebishev method, is presented. Only two elementary radiation patterns with opposite phase Side lobes were used as the base patterns in the first iteration. Synthesized radiation pattern deliberately has lower Side lobe level and another type of the amplitude reduction. m-degree cosine amplitude distribution with parameter in argument θ i which allows to control the side lobe level was investigated. Obtained amplitude distribution can be used as the basis for the synthesis of various radiation patterns for the Array antennas.
