Preliminary results on antenna testing in reverberating environments

In Antenna Radiation Pattern (ARP) measurements, echoes are regarded as spurious signals and any kind of reverberating environment is a priori not well adapted to carry out such operations. This belief is challenged here with the presentation of preliminary results related to two different techniques in reverberating media. The first one is based on the use of a generalized Time-Reversal principle in a reverberation chamber where a wavefront can be created on a given time interval - the second one is based on a setup where echoes are controlled but also regarded as useful sources of information.
