Title: Improvements in acoustics speedmeter logs
Inventor: LANGE GOESTA
IPC: G01S15/60
Filed: 1968-03-01
Abstract: 1,217,012. Doppler velocity log. C. LANGE. 1 March, 1968 [1 March, 1967], No. 10092/68. Heading H4D. A log for determining the speed of a craft relative to a surrounding medium from the Doppler frequency shift of acoustic echo signals from inhomogeneities in the medium is characterized in that its transmitter emits acoustic wave signals during a first limited time period and its receiver is operative only during a second time period whose beginning is delayed from the end of the first period, whereby echo signals from inhomogeneities in that part of the medium closest to and disturbed by the moving craft are not registered by the receiver. In the embodiment described a ship-borne transducer is supplied with a burst of carrier signal from an oscillator which is triggered at the beginning of each cycle of a square-wave from a timing generator. Echo signals returned to the transducer pass to a frequency meter (calibrated in terms of speed) via a gate which is opened for the second half cycle of each square-wave. This gating also eliminates disturbances due to electrical or acoustic signals affecting the receiver directly on transmission. Compensation for changes in the speed of sound in the medium with e.g. temperature, salinity or pressure is effected either (a) by arranging a thermistor near the transducer and coupling the thermistor to a bridge circuit which give a temperature-dependent output voltage for modifying the frequency meter indication or (b) by spacing one or more auxiliary transducers from the main transducer by a known distance in the direction of the sound propagation and comparing the phases or arrival times of the echo signals at the main and auxiliary transducers, to derive a voltage (dependent on sound speed) for correcting the frequency-meter indication.
