Antennas are usually measured in anechoic chambers in order to avoid multipath propagation. However, for electrically large antennas, the cost of building an anechoic chamber can become prohibitively high. In this thesis, novel measurement and signal processing techniques for echo suppression in antenna measurements that are performed in semi- or non-anechoic facilities are presented. The techniques are applicable to measurements acquired on arbitrary measurement geometries and do not place a restriction on the measurement probes. The techniques were validated through simulations and application to actual echoic measurement data.
