Free Space Radiation Pattern Reconstruction from Non-Anechoic Data Using the 3D Impulse Response of the Environment

Abstract

Using impulse response with a 3D algorithm is a novel free-space radiation pattern reconstruction technique with accuracy greater than 1 dB in all antenna under test (AUT) azimuth and elevation angle orientations inside a non-anechoic environment. A quantitative comparison between impulse response with a 3D algorithm and impulse response with 2D, a previous technique, is performed using quantifiers. Benefits of the proposed 3D free-space radiation pattern reconstruction algorithm are single-frequency characterization and reuse of the 3D impulse response of the environment.
