Patent number: 6842401Abstract: The present invention relates to sonar beamforming systems and methods, using a forward-looking sonar having transmit and receive transducer arrays with a beamforming device and at least one side-looking sonar having dynamically range-focused beams. The forward-looking sonar provides for obstacle avoidance and undersea survey. The systems include one-dimensional transmit and receive transducer arrays with beamforming electronics, a computing controller such as, for example, a personal computer host controller. The arrays and beamforming electronics can be packaged in a hermetically sealed housing unit and mounted in Unmanned Underwater Vehicles (UUV). The side-looking sonar system includes for example, 32-element, one-dimensional arrays that are mounted on either side of the UUVs. Further, a downward looking Bathymetric sonar may be mounted on the underside of the vehicle for high-resolution mapping.Type: GrantFiled: July 19, 2001Date of Patent: January 11, 2005Assignee: TeraTech CorporationInventors: Alice M.

Publication number: 20040104839Abstract: A wireless communication system employs directive antenna arrays and knowledge of position of users to form narrow antenna beams to and from desired users and away from undesired users to reduce co-channel interference. By reducing co-channel interference coming from different directions, spatial filtering with antenna arrays improves the call capacity of the system. A space division multiple access (SDMA) system allocates a narrow antenna beam pattern to each user in the system so that each user has its own communication channel free from co-channel interference. The position of the users is determined using geo-location techniques. Geo-location can be derived via triangulation between cellular base stations or via a global positioning system (GPS) receiver. The system can be optimized by applying partially adaptive processing algorithms, which are seeded by geo-location data.Type: ApplicationFiled: July 14, 2003Publication date: June 3, 2004Applicant: TeraTech CorporationInventors: Scott R.
