A large number of spatial room impulse responses can be measured efficiently by using a moving microphone in combination with a time-varying system identification method. The microphone moves on a predefined trajectory and captures the response of the acoustic system which is periodically excited. The instantaneous impulse responses are computed from the captured signal by taking the time-variance explicitly into account. In this paper, three different continuous measurement techniques are investigated and compared in a unified framework. It is shown that impulse response estimation constitutes a spatial interpolation process, where each method corresponds to a specific interpolation filter. In numerical simulations the performance of theses approaches are evaluated in terms of system distance and spatial bandwidth. |
