Claim Text:
1. A method for determining a direct antenna coupling in a reverberant environment, the method comprising: emitting radiowave energy in the reverberant environment from a transmitting antenna to a receiving antenna at a plurality of frequencies, wherein the reverberant environment comprises reflection surfaces entirely enclosing the transmitting antenna and the receiving antenna; collecting discrete frequency stirring data at each of the frequencies and at each of a plurality of angles to provide collected discrete frequency stirring data; correcting the collected discrete frequency stirring data for amplitude shift and frequency phase shift after all the collected discrete frequency stirring data has been measured using an expected amplitude shift and an expected phase shift at each of the frequencies and each of the angles to provide corrected discrete frequency stirring data; determining the direct antenna coupling based on the corrected discrete frequency stirring data; and determining at least one antenna pattern based on determined direct antenna coupling.
