Abstract
A method for determining a direct antenna coupling in a reverberant environment is disclosed. Radiowave energy is emitted in the reverberant environment from a transmitting antenna to a receiving antenna at a plurality of frequencies, and discrete frequency stirring data is collected at a plurality of frequencies. The discrete frequency stirring data is amplitude corrected and phase corrected using an expected amplitude shift and an expected phase shift at each of the frequencies to provide corrected discrete frequency stirring data. The direct antenna coupling is determined based on the corrected discrete frequency stirring data.
