A passive localization algorithm of supersonic object
Nudt Changsha · Applied Acoustics · 1998
A supersonic object generates a shock wave during its flight in the air.Utilizingthe arrival time of the shock wave, we present an algorithm based on the directional vec-tor of the wavefront to determine the speed and location of the object. We tested theeffectiveness of the algorithm by computing the estimation accuracy of a 3-station evenly-distributed circular array.
