| Summary: | Prototype measurements, an essential stage in the development of antennas, are normally performed in anechoic chambers. Although capable of providing high-fidelity data (owing to strict control of propagation conditions), such facilities are prohibitively expensive. A cost-efficient alternative involves measurements in a non-anechoic environment followed by post-processing of the responses. In this work, a multi-measurement correction of antenna far-field characteristics obtained in uncontrolled conditions is considered. The approach involves the synchronization and combination of non-anechoic data gathered at a few test setups so as to attenuate interferences and noise while augmenting a useful fraction of the signals. The approach has been validated using a Vivaldi antenna. Benchmark against the existing correction techniques has also been performed. |
