Latest Patents

Cyr's latest patents include a system for super short baseline navigation using phase-delay processing. This short baseline navigation system employs real-time estimation of the positions of multiple cooperative targets. Each target replies with a unique stepped frequency sequence signal that covers the usable frequency band. A processor operates on reply signals received by elements on the tracking platform and develops a coarse time-difference-of-arrival estimate using an algorithm derived herein. The processor also estimates the Doppler shift of received signals and determines a time-window that eliminates portions of the received signals corrupted by multipath interference. The relative phase differences between the received signals are then used in conjunction with the coarse time-difference-of-arrival estimates for precise direction-of-arrival estimation.

Another significant patent is for a long baseline tracking system. This method reliably locates the position of a submerged submarine with respect to a surface ship. A multiple number of transponders are placed at known locations near the sea floor, in the area of the ship and the submarine. One transponder has a dual function as both a response transponder and a relay transponder, while the other transponders function solely as response transponders. Elapsed times between the transmission of a first acoustic transmission pulse from the ship and receptions of first acoustic response pulses from the transponders are measured at the ship. These elapsed times are used to determine distances between the ship and the transponders, as well as distances between the transponders and the submarine. The location of the ship and the submarine, with respect to the transponders, are determined from these distances.
