Abstract: In order to analyze a sound field with a high spatial resolution, a large number of measurements are required. A recently proposed continuous measurement technique is suited for this purpose, where the impulse response measurement is performed by using a moving microphone. In this paper it is applied for the measurement of spatial room impulse responses on a spherical surface. The microphone captures the sound field on the sphere at discrete elevations while the system is periodically excited by the so-called perfect sequence. The captured signal is considered as a spatio-temporal sampling of the sound field, and the impulse responses are obtained by a spatial interpolation in the spherical harmonics domain. The elevation angles and the speed of the microphone are chosen is such a way that the spatial sampling points constitute a Gaussian sampling grid.
