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： A method of focusing fully-coherent circular synthetic aperture sonar (CSAS) imagery is provided. A k-space representation of the CSAS image is generated using the two dimensional Fast-Fourier Transform (FFT). Sub-aperture images are generated by windowing the k-space representation and applying the two dimensional inverse FFT to the windowed spectrum. All adjacent complex sub-aperture images are correlated, the correlation peaks are detected and the relative shifts in X and Y as a function of look-angle are recorded. The relative shifts between adjacent sub-apertures are integrated and the means are subtracted to find the absolute shift as a function of look-angle. A motion-solution is calculated by exploiting the relationship between apparent scene shift and actual vehicle sway. The motion estimation is used to generate a phase-correction matrix that is multiplied by the k-space representation of the fully-coherent image.

摘要： A transceiving device includes a transmission signal generating module for generating a transmission signal that is frequency-modulated by a predetermined frequency sweep width, a transceiver module for transmitting a pulse signal having substantially the same waveform as a waveform of the transmission signal and receiving an echo signal corresponding to the transmission signal from a detection range, and a pulse-compression filter for pulse-compressing the echo signal received by the transceiver module. The pulse-compression filter has an input/output characteristic. The characteristic has, when the pulse-compression filter is inputted with an input signal having substantially the same waveform as the waveform of the transmission signal, a window function shape such that a phase spectrum of an output signal corresponding to the input signal is linear and an amplitude spectrum of the output signal does not have a frequency component other than a frequency band with which a frequency sweep is carried out.

摘要： In an obstacle detection system, a wave transmitted by a transmitting element and received by receiving elements as a receiving wave includes extraneous waves, which are reflection waves from other than an obstacle, and obstacle reflection waves from an obstacle. It is determined that, an obstacle is present, if the reflection waves are detected as having an amplitude (voltage) greater than a threshold level and a reception time difference between time points at which the amplitude exceeds threshold level at the receiving elements is less than a predetermined time.

摘要： Noise discrimination in signals from a plurality of sensors is conducted by enhancing the phase difference in the signals such that off-axis pick-up is suppressed while on-axis pick-up is enhanced. Alternatively, attenuation/expansion are applied to the signals in a phase difference dependent manner, consistent with suppression of off-axis pick-up and on-axis enhancement. Nulls between sensitivity lobes are widened, effectively narrowing the sensitivity lobes and improving directionality and noise discrimination.
