Abstract
A method for determining the location of an impact on a surface () comprising N acoustic sensors (), transmitting a sensed signal s(t) to a processing unit () comprises the following steps (a) computing P intercorrelation products (b) calculating P inverse Fourier transforms p'(u) (c) computing for each area k, P(u)=ΣP′(u−τ); d) finding k, where a characterizing value of P(u) is greater than a given threshold value.
