Abstract

A mathematical model for calculating the effective scattering area (ESA) of an aircraft is presented. The model is based on the use of a two-step approach: calculation of the parameters of the reflected electromagnetic wave (EMW) in the vicinity of the aircraft (the classical finite-difference method of integrating Maxwell’s equations in a limited area of space, including an aircraft, is used). Stage 2 involves the calculation of the attenuation of the reflected EMW as it propagates from the aircraft to the radar’s receiving antenna (the method of Green’s functions is used, whose sources are the parameters of electromagnetic fields (EMFs) at the boundary of the calculation area of the first stage). This approach makes it possible to calculate the ESA of aircraft surrounded by ionized formations formed due to various physical effects. The 3D model is tested on well-known analytical solutions for calculating the ESA for simple geometric bodies (sphere, cylinder, rectangular plate).
