Abstract: Provided is a ship speedometer which is capable of measuring log speeds at individual water depths accurately to a depth where the log speed sufficiently grows. According to a representative aspect, in a fluid where the ship floats, a speed of a current is measured at a plurality of different water depths within a given measurement range, a theoretical curve of a log speed for individual water depths, provided in advance, is conformed to a distribution of the current speeds for the individual water depths, and a log speed at an arbitrary water depth within a deeper range of the measurement range is calculated based on the conformed theoretical curve.

Abstract: Improved two-dimensional planar array transducer and beamformer apparatus and methods. In one embodiment, the two-dimensional planar array transducer is capable of simultaneously or sequentially forming multiple acoustic beams in two axes and at two or more widely separated acoustic frequencies from a single flat planar array transducer. The transducer planar array consists of two or more electrically and acoustically independent two dimensional planar transducer array structures operating at different frequencies that are physically integrated onto a single multi frequency configuration. In an exemplary embodiment, a second higher frequency transducer array is positioned within the aperture area of a lower frequency planar array transducer. Methods of using the aforementioned two-dimensional planar array transducer and beamformer are also disclosed.

Abstract: The invention relates to a method for determining the speed (101) of a vehicle (100). At least one object (310, 320, 330, 340, 350, 360) located in the surroundings of the vehicle (100) is detected, and a speed of the detected object (310, 320, 330, 340, 350) relative to the vehicle (100) is measured. Furthermore, the speed (101) of the vehicle (100) is determined using the relative speed (311, 321, 331, 341, 351, 362) of the object (310, 320, 330, 340, 350, 360).

Abstract: In a process and with a device for non-contact measurement of speed on surfaces, in particular for ski speed measurement on snow surfaces, a signal (102) with a fixed frequency is beamed in the direction of travel (106) at a beam angle ( alpha ) which is less than a half aperture angle ( THETA /2) of the device (100) emitting the signal (102); a signal (110) reflected at the surface (104) and Doppler-shifted relative to the beamed signal (102) is received; from the Doppler spectrum of the received signal (110) that portion with the highest frequency and an energy value above a predetermined level is determined, and the speed is derived from the frequency of the determined portion of the spectrum.
