Abstract: A wideband sonar receiver is provided that includes: a selectable bandpass filter adapted to filter a received sonar signal to produce a filtered signal and a correlator adapted to correlate the baseband samples with baseband replica samples to provide a correlated signal. In addition, the wideband sonar receiver may include a shaping filter to shape unshaped received pulses. Finally, a variety of sonar processing algorithms are described with regard to reducing clutter and interference, target detection, and bottom detection.

Abstract: Embodiments of the invention provide apparatus (100) for detecting an erroneous measurement of a range of a target object 20 from a subject object 5. A transmitter transmits a signal (111S) having a first frequency from the subject object (5) to the target object (20). A detector (113) detects a portion of the signal (113S) reflected from the target object (20) back to the subject object (5); a controller is configured to determine the range (202) of the target object (20) from the subject object (5) by reference to a time of flight of the portion of the signal (111S), (113S) from the transmitter (111) to the detector (113); determine the rate of change of the range (203) by reference to a difference between the first frequency and an apparent frequency of the reflected portion of the signal (113S) detected by the detector; and provide an indication (206) that an erroneous measurement of range has been made if the range (202) increases while the rate of change of range (203) is negative.

Abstract: Die Erfindung betrifft ein Verfahren zum Bestimmen einer aus dem Doppler-Effekt resultierenden Doppler-Frequenzverschiebung 30 zwischen einem Sendesignal 4 und einem aus diesem Sendesignal 4 resultierenden Empfangssignal 20. Dazu wird eine Mehrzahl von relativen Frequenzverschiebungen um jeweils einen reellen Frequenzverschiebungswert durchgeführt, indem entweder wenigstens ein verschobenes diskretes Amplitudenspektrum 8 des Sendesignals 4 und wenigstens ein verschobenes diskretes Amplitudenspektrum 22 des Empfangssignals 20 oder jeweils eine Mehrzahl von verschobenen Amplitudenspektren des Sendesignals 4 oder des Empfangssignals 20 erzeugt werden. Zu diesen Frequenzverschiebungen werden Qualitätsmaße ermittelt, welche die Qualität der Übereinstimmung der verschobenen Signale angeben. Dasjenige Qualitätsmaß, welches der höchsten Qualität der Übereinstimmung entspricht, wird ermittelt und der zu diesem Qualitätsmaß zugehörige Frequenzverschiebungswert wird der zu bestimmenden Doppler-Frequenzverschiebung 30 gleichgesetzt.

Abstract: A novel method and apparatus are presented for use in analyzing and presenting Doppler data in a Doppler ultrasound system. At least one distance range from an ultrasound transducer along an ultrasound beam is controlled. This at least one distance range includes a plurality of successive locations between a first distance along the ultrasound beam and a second distance along the ultrasound beam. A Doppler signal spectrum representative of the plurality of locations within said at least one distance range is displayed in at least one display window, respectively.
