Реферат: This patent discloses a procedure in which only passive sensors are used to determine the range and direction of sound producing targets. To this end, it is proposed that in addition to the acoustic sensors that are usually required to determine the bearing angle, a seismic sensor is also used in order to measure the range to the target. Then, for a signal source that is characteristic of the target, a characteristic line is measured in both the airborne-sound and in the ground-sound spectrum, and the radial target speed (Vz,r) is determined from the Doppler shift of these lines and from the propagation speed (C) of the corresponding waves, when one computes the target range (r) from this, taking into account the bearing angle (.alpha.).
