Abstract:
1. Method for locating an impact on a surface belonging to an object provided with at least N SENS acoustic sensors, N SENS being a natural integer at least equal to 2, said method being implemented by a central processing unit linked to said acoustic sensors and in which method: the sensors are made to pick up respectively N i being an index between 1 and N there is calculated, for each reference point of index j, at least one validation parameter representative of at least one intercorrelation of complex phases representative of said picked up signals S the impact is located by determining at least one reference point as close as possible to the point of impact, by applying at least one validation criterion to the validation parameter, characterized in that said validation parameter is representative of at least one intercorrelation: where: φS φR * denotes the conjugate operator, applied to φS S R p is a non-zero natural integer less than or equal to N i
