The system is based on the two-microphone, transfer function test method, which means measurements take only a fraction of the time required by traditional, standing-wave ratio systems.
In a single bandwidth sweep the standing-wave ratio (SWR) can exceed six several times.
The measured and simulated ARs, broadside gains, and standing-wave ratios (SWRs) are shown in Figs.
