摘要： An ultrasonic measuring device includes an ultrasonic transducer without voltage converter having two transducer terminals to which an alternately reversible control voltage can be applied for emitting an ultrasonic burst signal in a control phase and to which an evaluation voltage is applied in a reception phase. The ultrasonic transducer decays in a decay phase between the control phase and the reception phase. A control unit generates the control voltage. The control unit comprises a full bridge circuit with two half bridge circuits, each comprising two semiconductor driving switches, which are connected to the two terminals of the ultrasonic transducer. An evaluation unit is provided with two input terminals, each of which is connected to the terminals of the ultrasonic transducer via a connection line. Voltage limiting elements in the two terminal lines limit the voltage applied to the input terminals of the amplifier.

摘要： A marine sonar system comprises a sonar transducer, an attitude sensor, and a processing element. The sonar transducer is configured to transmit a sonar beam into a body of water according to a transmit electronic signal, receive reflections of the sonar beam, and output a receive electronic signal according to the reflections of the sonar beam. The attitude sensor is configured to determine an attitude angle of a marine vessel with which the marine sonar system is utilized and to output an attitude electronic signal whose value varies according to the attitude angle. The processing element configured to receive the attitude electronic signal receive and, based on the attitude electronic signal, control the output of the transmit electronic signal to the sonar transducer.

摘要： An ultrasound circuit comprising a trans-impedance amplifier (TIA) with built-in time gain compensation functionality is described. The TIA is coupled to an ultrasonic transducer to amplify an electrical signal generated by the ultrasonic transducer in response to receiving an ultrasound signal. The TIA is, in some cases, followed by further analog and digital processing circuitry.

摘要： During transmission, a speed of sound pulses gradually reduces due to acoustic impedance. Regulating a length or a density or a sound speed of the sound pulses affects their average speed in the transmitting medium, sound intensity and detecting depth. Time of flight (TOF) and TOF shift can be used to calculate the depth and moving speed of detecting objects. Calculating a speed of moving objects by simultaneously detecting TOF shift at same site from two separated piezoelectric (PZT) elements improves the testing results with accuracy, simplification and reproducibility. Coding sound pulses to obtained the TOF and the TOF shift will simultaneously calculate the depth and the moving speed of sampling points, which can be used to construct 2D and 3D images for these motionless and/or moving sampling points. Coded sound pulses also improves the quality of the imaging.

摘要： In a method and system for inspecting the condition of a structure, the structure is scanned with a three-dimensional (3D) scanner. The 3D scanner includes a sensing system having one of a radar sensing device or an ultrasonic detection device. The sensing system detects 3D information about a subsurface of the structure, and the 3D scanner generates 3D data points based on the information detected by one or more of the radar sensing device and the ultrasonic detection device. A 3D model is constructed from the 3D data and is then analyzed to determine the condition of the subsurface of the structure.

摘要： The present invention provides a coherent radar system based on a modification of standard non-coherent radar without Moving Target Indication. Typical radars in this class are Navigation radars which are mass produced with low cost components. These radars utilize a magnetron in the transmitter which is a random phase device. In the present invention, the received signal is extracted just prior to amplitude detection process (where phase information is lost), and digitized using an analogue to digital converter providing coherent detection based on correlation between the transmitted pulse and the received signal.

摘要： A multi-dimensional beamforming device that performs consecutive one-dimensional operations. For example, beamsteering for a two-dimensional array can be include a projection of a beam onto each of the respective axes of the array. In such a device, a first beamforming processing element is used to form multiple beams for each array output along a given row. In a preferred embodiment, sequential output vectors from the first processing element are then applied to a transposing or corner turning memory and the data are reformatted such that all elements on a given column of the array are applied to a second beam forming processing element.
