    • The present invention applies model-based processing to a sensor output from a sensor such as a sonar, radar, or laser range finder. In particular, embodiments of the invention use a priori knowledge of a model signal return expected from a particular object to identify the location of the object relative to the sensor (and/or vice versa). In some embodiments the object is augmented with reflectors that return the sensor signal back towards the sensor so that the object can be more easily detected by the sensor. In preferred embodiments the reflectors are arranged in an a priori known pattern on the object, to help identify both the location and the orientation of the object with respect to the sensor. In the preferred embodiment, the sensor is a sonar, mounted on an unmanned underwater vehicle (UUV).
    • 本发明将基于模型的处理应用于诸如声纳,雷达或激光测距仪的传感器的传感器输出。 特别地,本发明的实施例使用从特定对象预期的模型信号返回的先验知识来识别对象相对于传感器的位置(和/或反之亦然)。 在一些实施例中,用反射器增强物体,反射器将传感器信号返回到传感器,使得物体可以被传感器更容易地检测。 在优选实施例中,反射器以先前已知的图案布置在物体上,以帮助识别物体相对于传感器的位置和取向。 在优选实施例中,传感器是安装在无人水下飞机(UUV)上的声纳。

    • In a method for determining absolute position under water of a submersible vessel (1) having a dead reckoning navigation system and receiving acoustic signals from a reference station (19), signals are received from one reference station in several positions (15-18) of the vessel. Estimated absolute positions of the vessel are calculated using range data and relative position data. Range rate derived from the signals are preferable utilised. In a method for scanning an underwater survey area, the absolute position of a vessel (1) is intermittently being determined according to said method. The reference station may be placed at a fixed absolute position (19), or on the surface of the water, preferably in a buoy or a vessel. A system for determining the absolute position under water of a vessel comprises: acoustic communication means in a reference station and on board the vessel; a dead reckoning navigation system on board the vessel; and computing means.

    • A system and method for determining a location. The system employs encoded information devices dispersed through the environment, each having a non-unique code associated therewith. The codes from the encoded information devices are acquired as a reading device passes nearby, and stored. The codes from a proximate set of information devices are correlated with a map or mapping relation to determine one or more consistent positions within the environment. The information devices are preferably passive acoustic wave transponders, and the mapping relation may be a pseudorandom sequence or a defined map.
