Method for locating an impact on a surface and device for implementing such a method
Abstract:
Method for locating an impact on a surface (9), in which acoustic sensors (6) pick up acoustic signals ski (t) generated by the impact and the impact is located by calculating, for a number of reference points of index j, a validation parameter representative of a function: PRODkji1i2. . . i2P(ω)=φSki1(ω) φRji1(ω)*φSki2(ω)*φRji2(ω) . . . φSki2p(ω)*φRji2p(ω) where: φSki(ω) and φRji(ω)* are complex phases of Ski(ω) and of Rji(ω), for i=i1, i2, . . . , i2p, indices denoting sensors, Ski(ω) and Rji(ω) being the Fourier transform of ski(t) and rji(t), rji(t) being a reference signal corresponding to the sensor i for an impact at the reference point j, p being a non-zero integer no greater than NSENS/2.
Abstract(Chinese):

用于定位对表面（9）的冲击的方法（9），其中声学传感器（6）拾取由冲击产生的滑雪（t）的声学信号，并且冲击位于通过针对索引j的多个参考点计算a 表示功能的验证参数：PRODkji1i2。 。 。 i2P（omega）= phiSki1（ω）phiRji1（ω）* phiSki2（ω）* phiRji2（ω）。 。 。 phiSki2p（omega）* phiRji2p（omega）其中：对于i = i1，i2，phiSki（ω）和phiRji（ω）*是Ski（ω）和Rji（ω）的复相。 。 。 ，i2p，表示传感器的索引，Ski（ω）和Rji（ω）是滑雪（t）和rji（t）的傅立叶变换，rji（t）是对应于传感器i的参考信号，用于参考的影响 点j，p是不大于NSENS / 2的非零整数。
