Free-Space Antenna Factor Computation Using Time-Domain Gating and Deconvolution Filter for Site Validation of Fully Anechoic Rooms

An alternative method to compute the free-space antenna factor using time-domain transformation and deconvolution filter for pulse compression is proposed. The deconvolution filter helps in compressing the time-domain pulse to distinguish the direct wave from the reflected wave and help evaluate the...

Description
Summary:An alternative method to compute the free-space antenna factor using time-domain transformation and deconvolution filter for pulse compression is proposed. The deconvolution filter helps in compressing the time-domain pulse to distinguish the direct wave from the reflected wave and help evaluate the free-space antenna factor for site validation of fully anechoic rooms. The antenna pair of ETS-Lindgren Model 3110C and 3180C antennas, simulated with numerical electromagnetics code, is subjected to the proposed method with deconvolution filter and Wiener filter. Based on the simulation results, the proposed method is implemented over the measured results of the antenna pair and used for the site validation of a fully anechoic room. The free-space normalized site attenuation results of the fully anechoic room comply with the ±4 dB specification.
