| titleOfInvention | Method and device for extracting a useful signal of finite spatial extension at each instant and variable with time. |
| abstract | The invention relates to a method of extracting a useful signal of finite spatial extension and variable with time by an array of N sensors, N being greater than or equal to 3, receiving this useful signal added to q coherent additive noises. spatially, q being less than N, comprising the following steps: - a step (42) of acquiring the raw signals on the output of each sensor; a step (43) of band-pass filtering of said signals in order to be restricted to the frequency band of the useful signals; - a step (44) of digitizing said filtered signals; a step (46) of calculating the noise spatial prediction error signals; a step of analyzing the prediction error signals so as to detect the useful signal and its separation from the q additive noises. The invention also relates to a device for extracting a useful signal. Application in particular to the field of magnetic detection. |
