摘要： A passive method for obtaining target data from a sound source disposed in a nonsolid medium by means of a sound receiver remote from the sound source, by the steps of: providing, as the sound receiver, first and second sound-to-electrical signal transducers constituted and positioned to each respond to a respective one of two sound waves propagated from the sound source to the sound receiver at respectively different propagation speeds; and deriving, by means of an electrical signal processing system connected to receive output signals from the transducers, target data from the sound source by determining the frequencies of, or the difference in reception time between, the sound waves emitted by the source and to which the two transducers respond.

摘要： A method for classifying vehicles passing a predetermined waypoint, for a refined classification within specific vehicle categories such as tracked or wheeled vehicle categories, where the distance to the vehicle passing the waypoint is continuously actively optically measured along a measuring line extending through the waypoint, from a fixed measuring location disposed transversely on the side of the road, and the speed of the vehicle passing the waypoint is additionally measured. The spatial distance between the measured values in the direction of the longitudinal axis of the vehicle is determined from the vehicle speed and the measuring frequency, and a measurement profile of the undercarriage of the vehicle is created by plotting the measured values spaced at the specific spatial distance in the direction of the longitudinal axis. The measurement profile is compared, either indirectly by the derivation of undercarriage parameters, such as number of axles, axle spacing and wheel diameter, or directly with known reference vehicles. The vehicle is classified as that reference vehicle for which the coincidence or correlation is the greatest.
