Research On The Electromagnetic Properties Of Radome

The research on the electromagnetic properties of radome has been paid attention extensively, some studies on two kinds of analysis method are presented in the dissertation. First, the Gauss Integration is combined with the plane wave spectrum-surface integration method (PWS-SI) to analyze the electromagnetic properties of the radome. Difference spectrum of the aperture antenna is used for calculating the difference far-field of the antenna-radome structure, and the Gauss integration is applied to the PWS-SI method to improve its precision. An olivary radome is calculated and analyzed. The results illustrate the efficiency of the method in this paper. Secondly, the conjugate gradient-fast fourier transform method (CG-FFT) is analyzed thoroughly. The RCS of objects can be derived by solving the electric field integral equation (EFIE) with CG-FFT. With a suitable set of basis and testing functions chosen to discretize the EFIE, the scattering field is calculated by the current obtained through the equation using the CG and FFT method. Finally, some typical geometries are analyzed. The simulation results show that this CG-FFT scheme avoids the storage of large matrices and reduces the computation time.
