摘要： The invention is a method for improved active sonar using a singular value decomposition filtering and a Volterra-Hermite Basis Expansion to model real active sonar measurements. The fitting model minimizes the sum of the squared errors between a measured channel response, z(t), and model response, y(t), which is a fitted Volterra Series solution. The model requires as input an excitation waveform, x(t), to which is fitted the model response, y(t). A contracted broadband cross-ambiguity function is used to correct the excitation waveform for Doppler and range effects. Once completed, the modeled response can be used to determine the linearity or non-linearity of the channel effects. Appropriate measures can be utilized to reduce these effects on the measured channel response.

摘要： An object is detected without being constrained by the positional relationship between the object and the detecting position. A detection device includes a pseudo sound source and a monitoring unit. The pseudo sound source generates a scanning sound wave of a phase-conjugate wave in the time domain based on an acoustic signal by performing active phase conjugation, and causes the scanning sound wave to converge on the detection object from the above thereof within the propagation space by utilizing a feature that the scanning sound wave converges on the pseudo sound source which is the generation source of the acoustic signal. The monitoring unit extracts a reflected sound wave which is reflected at the detection object from the sound wave in the propagation space by performing passive phase conjugation. The detection object is detected based on presence or absence of the extracted reflected wave.

摘要： A downscan imaging sonar utilizes a linear transducer element to provide improved images of the sea floor and other objects in the water column beneath a vessel. A transducer array may include a plurality of transducer elements and each one of the plurality of transducer elements may include a substantially rectangular shape configured to produce a sonar beam having a beamwidth in a direction parallel to longitudinal length of the transducer elements that is significantly less than a beamwidth of the sonar beam in a direction perpendicular to the longitudinal length of the transducer elements. The plurality of transducer elements may be positioned such that longitudinal lengths of at least two of the plurality of transducer elements are parallel to each other. The plurality of transducer elements may also include at least a first linear transducer element, a second linear transducer element and a third linear transducer element. The first linear transducer element may be positioned within the housing to project sonar pulses from a first side of the housing in a direction substantially perpendicular to a centerline of the housing. The second linear transducer element may be positioned within the housing to lie in a plane with the first linear transducer element and project sonar pulses from a second side of the housing that is substantially opposite of the first side. The third linear transducer element may be positioned within the housing to project sonar pulses in a direction substantially perpendicular to the plane.

摘要： This disclosure provides a fish finder, which includes a transmission module and a reception module, for outputting an ultrasonic wave underwater, receiving an echo, and outputting a reception signal corresponding to an intensity of the received echo, a control module for generating echo data corresponding to a depth based on the reception signal, a display module for displaying the echo data, and a user interface for receiving a user's operation. The control module causes the display module to display the echo data so that the echo data is displayed in two or more display screens. At least one display screen displays an area having a color different from a background color. A part of the echo data at a depth range corresponding to a height of the area is displayed in the other display screen so as to expand the echo data in a depth direction. The user interface specifies a position and a size of the area via the user's operation.

摘要： Methods and apparatuses for finding, extracting and for providing of echoes with detail functions are described. In particular, an echo extraction method for extracting an echo from an echo function is described. The method comprises receiving the echo function and decomposing the echo function in at least one detail function. The at least one detail function comprises a plurality of first coefficients. Each of the at least one detail functions represents a different degree of detail of the echo function. The degree of detail relates to a form of a base function. Furthermore, the method comprises eliminating at least one of the plurality of first coefficients and applying a reconstruction regulation or scheme, which depends on the form of the base function, for generating a smoothed echo function. Thereafter, at least one echo is determined from the smoothed echo function.
