... waveguides with a random cross section shape that made it possible to obtain new facts about the characteristics of waveguide monopulse AAs having a broader working frequency band as compared to the traditional arrays made of rectangular and circular waveguides (not less than 25%) in a wide section of single–lobe scanning (not less than ±120°) on linear and circular polarizations. — Proposing the universal mathematical apparatus and creating an applied set of algorithms and software for researching and optimizing the radiation and distribution systems of AAs, microwave devices and channels based on waveguides with a random cross section shape making it ...
