    摘要: Provided are a sonar system and transducer assembly for producing a 3D image of an underwater environment. The sonar system may include a housing mountable to a watercraft having at least one transducer array. The transducer array may include a transmit/receive element configured to transmit sonar pulses and a second transducer element. The transmit/receive element and the second transducer element may receive first and second sonar returns convert the first and second returns into first and second sonar return data. A sonar signal processor may then generate a 3D mesh data using the first and second sonar return data and at least a predetermined distance between the transducer elements. An associated method of using the sonar system is also provided.

    摘要: Provided are a method, apparatus, and computer program product for updating stored 3D mesh data from live 3D mesh data. The method may include processing, by a sonar signal processor, first sonar return data and second sonar return data from first and second transducer elements of at least one transducer array to generate live 3D mesh data. The method may include determining a position associated with the live 3D mesh data that corresponds to the position of the watercraft when the first sonar return data and the second sonar return data was received, and may include updating a stored 3D mesh data with at least a portion of the live 3D mesh data based on the position.

    摘要: A scene is reconstructed by transmitting pulses into a scene from an array of transmitters so that only one pulse is transmitted by one transmitter at any one time. The one pulse is reflection by the scene and received as a set of signals. Each signal is sampled and decomposed to produce frequency coefficients stacked in a set of linear systems modeling a reflectivity of the scene. Then, a reconstruction method is applied to the set of linear systems. The reconstruction method solves each linear system separately to obtain corresponding solutions, which are shared and combined to reconstruct the scene.

    摘要: The target searching device includes: a sound source which transmits a sound wave into a propagation space; a transducer array placed in an area to receive a forward scattering wave which scatters forward from the target within the propagation space; a subtraction processing device which subtracts a traveling wave directly traveling towards the transducer array from a mixed wave of the forward scattering wave and the traveling wave so as to separate the forward scattering wave; a passive-phase conjugate processing device which performs passive-phase conjugate processing on the forward scattering wave separated by the subtraction processing device so as to generate a passive-phase conjugated signal of the forward scattering wave; an autocorrelation processing device which performs autocorrelation processing on the traveling wave to generate an autocorrelation processed signal of the traveling wave; and a correlation device which judges a similarity between the autocorrelation processed signal and the passive-phase conjugated signal.
