  • Patent number: 9581623
    Abstract: A band power computation device with which the amount of calculation required to compute channel power is reduced, and with which it is possible to obtain channel power with the same precision as when the channel power is obtained from the entire input signal. With this device, a subspace extraction unit (101) extracts a portion of the input signal. An FFT unit (104) performs a Fourier transformation on the extracted signal, generating a spectrum signal. A power computation unit (105) computes the channel power for each frequency from the spectrum signal. A power generation unit (150) expands the channel power to the same channel power as the channel power computed from the input signal, and smoothes the expanded channel power by performing a calculation sequentially from the highest frequency to the lowest frequency, said calculation using the expanded channel power and a prescribed constant.

  • Patent number: 9264642
    Abstract: Conventionally, in order to obtain a difference signal between an A+N signal and an N signal and a difference signal between an A+B+N signal and the A+N signal, the A+N signal needs to be held in two different capacitors. Hence, there is a problem in that, due to variations in capacitance of the two capacitors, the difference signal between the A+N signal and the N signal and the difference signal between the A+B+N signal and the A+N signal may not accurately be obtained. An imaging device generates a signal obtained by subtracting the same digital N signal from each of the digital A+N signal and the digital A+B+N signal.

  • Patent number: 7746225
    Abstract: Disclosed herein is a fast method that locates nearby sources based solely on the time-of-flight of a signal across an array of sensors. The time delay for signal passage between all pairs of sensors is determined using cross-correlation estimates and a vector of time delays, ?, is constructed from the results. In the noise free case, each point in the plane is associated with a unique value of the ? vector. The plane is searched for a source location by minimizing the difference between the value of ? associated with the candidate location on the plane and the value estimated from cross-correlations. The search takes place over the three dimensional space that includes two coordinates in the plane and the propagation speed. The starting point for the search is constructed from an analytic fit of circular wave fronts to groups of sensors within the array.

  • Patent number: 7592899
    Abstract: A telemetry system is described in which a plurality of channels are coupled to a bus. A control subsystem controls the channels so that one of the channels presents to the bus during its designated time period a channel characteristic. The control subsystem interrogates in the analog domain each of the channels during its designated time period, and forms a signal representative of the channel characteristic. The control subsystem may combine one or more of the signals into a digital packet, and transmit the same via transceiver over a wireless network. The channels may be contained within a submersible enclosure and displaced at intervals along the bus, thereby forming an array for monitoring waterborne threats. The array may lie along an ocean floor, may be towed by a marine vehicle, or may suspended from a deployable buoy containing the control subsystem, transceiver, and a remote power source. The array may further comprise a defensive countermeasure deployable responsive to detecting a threat.

  • Patent number: 7245559
    Abstract: Methods and apparatus determine if an underwater intruder passes under a protective boundary. A sonar sensor system comprises a plurality of sonar sensor modules that are spaced on a protective boundary. A sonar sensor module comprises a sonar transducer (sonar array) that is characterized by an omni-directional radiation pattern that may overlap an omni-directional radiation pattern of an adjacent sonar sensor module transducer. The sonar sensor module collects sonar data such as range information of the target in relation to time. A central processor obtains the sonar data from each sonar module through a telemetry link. The central processor processes the sonar data from the plurality of sonar sensor modules in order to determine an estimated path of the target and may determine if the target should be considered as a threatening underwater intruder from a calculated threat level estimate based on this data.

  • Patent number: 6928030
    Abstract: A set of seismic detectors is distributed throughout a defense zone in communication with a set of attack or other controllable devices. A seismic signal source controlled by a zone defense coordinator communicates at scheduled times to the seismic detectors and through them to the associated devices to convey mission critical information. The seismic detectors and the attack devices are controlled singularly and/or collectively by self-contained processors. The seismic source may be at a fixed site and is substantially repeatable as well as controllable. The system may be specially adapted to a wide range of terrains including land and water; and from very shallow to very deep water. Targets may be characterized in terms of their typical seismic signatures and the same hardware system used for seismic communication may be also programmed for target detection and device activation.
