  • Publication number: 20220344793
    Abstract: An antenna module configured for use on an underwater vehicle is disclosed. The antenna module includes an array of spiral antennas fabricated on a multi-layer substrate that provides wide-band RF communication with direction finding (DF) capability. The antenna module can also include other antennas fabricated on the same multi-layer substrate, such as one or more global positioning system (GPS) receivers, an ultra-high frequency/very-high frequency (UHV/VHF) antenna, or one or more iridium antennas. The antenna module may further include a water-proof housing that is coupled to the outside hull of an undersea vehicle via a coupling mechanism. The coupling mechanism allows the antenna module to rotate between a stowed position against the hull and a deployed position that extends the antennas out away from the undersea vehicle. The antenna module is curved or flexible so it can stow against a corresponding curved hull of the undersea vehicle.

  • Patent number: 11474365
    Abstract: The system and method for imaging having filter containing polarized elements, multispectral elements or both being oscillated in circular or linear motion so each individual pixel will view a scene thru the individual filters. The motion of the filter is synchronized with a frame rate of an imager. In one example this is accomplished by micro actuators. Each pixel sampling feeds a processor detection algorithm that determines if a multispectral/polarization signature is present in the scene.

  • Publication number: 20220329223
    Abstract: Techniques are provided for automatic gain control processing to reduce adverse effects associated with clipped samples resulting from conversion of analog signals to digital signals. A methodology according to an embodiment includes identifying a clipped sample of the digital signal, for example by comparison of the digitized sample values to a threshold value associated with a full scale value of the converter. The method also includes applying a window function to portions of the digital signal. The window function is configured to attenuate samples of the digital signal within a region centered on the identified clipped sample. A Hilbert finite impulse response (FIR) filter may be applied to the digital signal prior to applying the window function. Parameters of the window function are selected based on frequency response characteristics of the FIR filter and on signal to noise ratio requirements of an application that receives the windowed digital signal.

  • Patent number: 11460272
    Abstract: The system and method of a dual mode semi active laser seeker and imaging system using pulse detection and angle determination as applied to quad detectors to properly identify a correct designator spot. The angle performance is driven by the field of view of the imaging system. The imaging system resolution provides the required angle accuracy for guidance as cued by pulse detection apertures. The imaging system eliminates the need to designate until impact thus eliminating exposure to counter fire against the designator. The elimination of designation until impact also opens up the opportunity rapid engagement of multiple targets from a single designator.

  • Patent number: 11462879
    Abstract: A system and method for enhancing laser contrast on a remote target utilizing an image processor and a laser power controller is provided. An image processor in an imaging device manipulates a laser power controller in a laser system so that a laser beam emitted from a laser system is ultimately synchronized with the imaging device. Firstly, the original laser signal is shifted one time frame relative to the plurality of time frames to create a shifted laser signal. Secondly, the shifted laser signal is subtracted from the original laser signal. Thirdly, the subtracted laser signal is magnified by a frequency band pass filter. The filtered laser signal is added to the original signal to become the finalized laser signal which has better contrast than the original signal.

  • Patent number: 11438529
    Abstract: Systems for detecting a presence of a microbolometer are provided. The systems may also discriminate a type of the microbolometer. The systems may comprise analog filtering and processing or digital filtering and processing. In some examples, both analog and digital filtering may be used. For example, a system may comprises a photodiode, an analog to digital converter (ADC) having a frequency sampling rate of at least two times an expected frequency range of known microbolometers and a processor. The ADC may receive an amplified output from the photodiode and produce a sampled sequence using the frequency sampling rate. The processor converts the sampled sequence into a frequency profile, examines the frequency profile to identity at least a fundamental frequency and determines whether a microbolometer is detected in a line of sight of the photodiode based on the fundamental frequency.
