Inhalt:
A novel approach for model-based interpolation of sampled antenna pattern in azimuth, elevation and frequency domain is presented. Using wavefield modelling, an algebraic antenna model is derived, which incorporates Fourier transformation and is stated as Effective Time-Aperture Distribution Function (ETADF). A method to automatically de-noise sampled antenna pattern by estimating the model order is proposed. Furthermore, numerically efficient interpolation of antenna pattern data from the ETADF is presented. The ETADF approach is validated on simulation data of a conical horn antenna.
