Suppression of scattering waves by optimizing the geometric design of radome seams using simulated annealing method

摘要

Large sandwich radomes are constructed by connecting small panels for the restrictions on manufacture. These connection parts produce undesired scattered waves and generate higher sidelobes. We present a novel method of sidelobes suppression by optimizing the radome geometric design. At 'first the scattering characteristics of radome seams are analyzed by using physical optics technique with some corrections. Simulated annealing method realizes optimized radome geometry that has well-behaved sidelobes. Calculation results show the validation of our proposed method.
