| 105 | Method for global acoustic positioning of a marine or submarine target | US13452373 | 2012-04-20 | US08767511B2 | 2014-07-01 | Sébastien Pennec; Pierre-Yves Morvan |
| A method for the global acoustic positioning of the USBL or SBL type of a marine or submarine target is more accurate than the method used by known USBL or SBL systems, while applying a network of sensors having the same material dimensions as those of these known systems. The method makes use of the movements of the network of sensors to apply principles of the processings by synthetic antenna. The principle of the synthetic antenna transposed to the present problem consists in using the signals received by the hydrophones of a physical antenna placed on a moveable platform at K different moments in succession, and therefore at K locations in succession in order to provide an estimate of the position of the beacon by virtue of an antenna of virtually greater dimensions. | ||||||

| 112 | HARBOR FENCE | US11265150 | 2005-11-03 | US20070133350A1 | 2007-06-14 | Larry McDonald |
| Methods and apparatus determine if an intruder passes into a security zone that is associated with a waterfront asset. An embodiment of the invention provides a harbor fence system that is designed to be deployed in water around ships or other waterfront assets to serve as a line-of-demarcation in order to provide protection. The harbor fence system comprises a series of spars that protrude above the water surface and that are connected with an electrical computer with a telemetry subsystem. Each spar contains electronic sensors, e.g. water immersion sensors and accelerometers, and circuitry to detect an intrusion and to communicate the location of the intrusion to a computer control station. The embodiment also facilitates deploying and retrieving the harbor fence system. Additionally, the embodiment may also determine whether an underwater intruder is passing under a protective boundary, in which the harbor fence system interfaces to an underwater sonar sensor subsystem. | ||||||
| 113 | Sonar bearing estimation of extended targets | US91473 | 1987-08-31 | US5949739A | 1999-09-07 | Sudha S. Reese |
| An improved bearing estimation sonar system provides high resolution imaging of extended multi-highlight targets at long ranges. The complex outputs of a pair of offset-phase centered beams are first processed by segmented replica correlators to achieve pulse compression, followed by cross-correlation to provide high fidelity bearing estimates for target imaging. The technique exploits space-time coherence properties of the target receive signal to extract high resolution target information. The processing employed in the system also includes data editing schemes resulting in enhanced discernability of submarine-like targets which is essential for target classification. Substantial processing gains are realizable by the system of this invention. | ||||||
| 114 | Method and device for sensing of obstacles for an autonomous device | US718399 | 1996-09-30 | US5867800A | 1999-02-02 | Edlund Leif |
| The present invention provides a method and a system for proximate field orientation of an autonomous device and utilizes a transmitted wave having a first frequency of slow propagation, whereby reflections from obstacles within a proximate area are detected. According to the present invention receivers are arranged in a slanted plane or preferably along a curved base-line to, in a simple way, obtain a three-dimensional direction to an obstacle reflecting the frequency of slow propagation. Additionally, an absorber or a screen or a combination thereof is arranged above at least one receiver to act as an "eyebrow" attenuating undesired reflections which at the receiver come from overhead. Additionally, at least one of the receivers along the generally curved base-line is arranged differently in height in relation to the remaining receivers, and preferably the most outer receiver on each side in the line of receivers along the generally curved base-line is arranged differently in height in relation to the remaining receivers for an improvement of the three-dimensional resolution. | ||||||
| 115 | Apparatus for and method of doppler motion detection with standing wave drift compensation | US675033 | 1984-11-26 | US4661936A | 1987-04-28 | Mark R. Magee; Richard E. Saffran |
| Drift of the standing wave pattern in an acoustic doppler intrusion detection system in a confined space is compensated by adjusting the relative radiating and receiving positions of the radiator and receiver transducers, respectively, either mechanically or electrically until the signal level of the carrier wave at the receiver transducer is optimized. In the mechanical adjustment mode, either the receiver transducer or the radiating transducer is supported for movement relative to the other and is moved by a motor energized under the control of a signal level sensor circuit connected to the output of the receiver transducer. In another mode, a plurality of receiver (or alternatively radiator) transducers are connected through a switch to the signal level sensor circuit which in response to a drop in received signal level below a predetermined threshold, selectively switches the active transducer to optimize the received signal level. In still another mode, one of at least two radiator (or alternatively, receiver) transducers is connected through a variable phase shifter to the signal generator (or to the receiver circuit for the receiver transducer), the phase shifter being adjustable in response to the output of the signal level sensor to optimize the signal level at the receiver transducer. The invention comprehends the apparatus for and method of optimizing signal strength at the receiver transducer. | ||||||
