摘要： A nonuniform pulse sonar system employing Doppler information for navigational purposes is disclosed. A train of pulses including a plurality of energy pulses having varying predetermined widths and spacing is provided by a nonuniform pulse generator to energize a transducer which serves as a projector adapted to transmit acoustical energy into a body of water. Reflected energy is sensed by the transducer, which also serves as a hydrophone, and subsequently processed by a tracker which selects and reproduces, as a continuous frequency signal, the predominant frequency in the frequency spectrum of the reflected energy detected. A demodulator unit is employed to compare the continuous frequency signal with the frequency of the energy pulses used to energize the transducer, the frequency difference constituting a Doppler frequency that is proportional to the velocity of a craft, on which the sonar system is mounted, relative to the object, or objects, such as the ocean floor, from which the transmitted energy is reflected.

摘要： A method for imaging formations below the bottom of a body of water includes imparting acoustic energy into the formations along a predetermined length swath at a selected geodetic position. Acoustic energy reflected from the formations is detected along a line parallel to the length of the swath. The selected geodetic position is moved a selected distance transverse to the length of the swath. The imparting acoustic energy, detecting acoustic energy and moving the geodetic position are repeated until a selected distance transverse to the length of the swath is traversed. The detected acoustic energy from all the selected geodetic positions is coherently stacked. The detected acoustic energy is beam steered to each of a plurality of depths and positions along the length of the swath to generate an image for each such depth and position.

摘要： Individual elements of a sonar receiver transducer provide output signals in response to the receipt of acoustic energy and signals are processed to form one or more receiver beams for display. Each element output is provided to a preamplifier to which is applied a time varied gain function. The output signal of at least one of the preamplifiers is additionally provided to an adaptive time varied gain circuit which generates an error signal for correction of the time varied gain function applied to the preamplifiers.
