1. A method of taking bearings on sharp reports, in which the acoustic pressure oscillations from each report are picked up at at least two measuring points (MS; MS1, MS2, MS3) equipped with at least two sound detectors (M1, M2, M3), the time differences in the arrivals of the acoustic pressure oscillations at the sound detectors (M1, M2, M3) at the same measuring point are determined for each measuring point (MS; MS1, MS2, MS3) and the corresponding time differences are transmitted to one central evaluation point (AS) for the determination of the place of origin (SO) of the report, characterised in that the time of arrival of the acoustic pressure oscillations of each report at the individual sound detectors (M1, M2, M3) at each measuring point (MS; MS1, MS2, MS3) is established and stored, that the time differences in the arrivals of the acoustic pressure oscillations at the sound detectors (M1, M2, M3) at the same measuring point (MS; MS1, MS2, MS3) are stored after the determination for each measuring point (MS), and that at the location of each measuring point (MS; MS1, MS2, MS3) from the time data and time difference data the direction of incidence of the sound (r; r1, r2, r3) and the time of incidence of the sound for the measuring point (MS; MS1, MS2, MS3) in question are determined electronically, after which these data are transmitted to the central evaluation point (AS) for the determination of the place of origin of the sound (SO) and of the time of origin of the sound. |
