Abstract:

A presentation of data processing techniques developed to obtain bearing angle estimates of plane sonic waves using arbitrary ground arrays of microphones. The evaluation of the accuracy obtainable as measured by the rms bearing angle error is computed in detail for a proposed 16-station square array for use in the VELA detection system. A novel feature of the method is that the ground trace velocity of sound need not be already known or measured independently, but can be derived from the same measurements as the bearing angle.
