A new method for optimizing RCS of the nose of flying objects

Abstract

This article aimed to optimize radar cross section (RCS) of the nose of flying objects using a new shaping method. In this method, parameters related to the scatterer shape can continuously change. Thus, precise optimization can be carried out. The nose of flying objects with desired size and sharpness was defined by mathematical formula with two parameters. The physical optics method was also applied to calculate RCS. Design curves were calculated by changing sharpness and size criteria of the nose of flying objects. Effects of changing frequency, angle of observation, and angle of incidence on RCS curves were also investigated. © 2015 Wiley Periodicals, Inc. Microwave Opt Technol Lett 57:1361–1365, 2015

Parallel body‐shaping of electrically large objects described by NURBS surfaces

“…Some related articles exist in the literature that deal with body‐shaping of perfectly conducting objects 24–27 . To provide a fair comparison and highlight our proposed method's strengths and weaknesses, these works will be briefly reviewed.…”

“…The main drawback is requiring many iterations and several frequencies to retrieve the location of the object accurately which takes a considerable amount of time. The work of Hoseini et al 25 presented a technique to optimize RCS of the nose of a flying object by modifying the sharpness and size of the nose. However, this method is more of a trial and error method than an inverse scattering problem.…”

“…Some related articles exist in the literature that deal with body-shaping of perfectly conducting objects. [24][25][26][27] To provide a fair comparison and highlight our proposed method's strengths and weaknesses, these works will be briefly reviewed. The articles are discussed based on the following metrics: object geometry, problem formulation and objective, the scattered field calculation method, and computational efficiency and accuracy.…”
