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.

Abstract: A wideband chaotic waveform that is rateless in that it may be modulated at virtually any rate and has a minimum of features introduced into the waveform. Further, the waveform provided may be operated below a signal to noise ratio wall to further enhance the LPD and LPE aspects, thereof. Additionally, the present disclosure may provide a mix of coherent and non-coherent processing techniques applied to signal samples to efficiently achieve coarse synchronization with a waveform that is faster, more efficient and more accurate than using time domain signal correlators alone.

Abstract: Techniques are provided for employing an embedded software defined radio (SDR) in a navigation system. A navigation system implementing the techniques according to an embodiment includes a global positioning system (GPS) receiver configured to acquire and track received GPS signals. The system also includes an SDR configured to process received communication signals. The communication signals include timing data. The SDR is further configured to calculate position and navigation data based on a combination of the processed communication signals and the tracked GPS signals provided by the GPS receiver. The system further includes a system timer configured to provide a common time base for use by the GPS receiver and the SDR. The navigation system is implemented in an application specific integrated circuit (ASIC).

Abstract: An underwater imaging system is carried by a submersible platform to capture images that are processed into three-dimensional images stitched together to create a 3D dimensional video at video rate speeds that are transmitted to a control unit above the surface of the water. The imaging system utilizes a high speed image sensor or camera to capture sequential gated images that are synced via a gating module to two sequential laser beam pulses. The laser beam pulses illuminate an object in each gated image. When the object is within a gate overlap region, the two images may be processed using 3D imaging techniques to generate a 3D representation of the object in the overlap region of the two gates.

Abstract: The present disclosure relates generally to a network system having multiple users, multiple inputs, and multiple outputs to transmit data from a data source through a link to a data sink. One example of a Multi-user multiple input multiple output (MU-MIMO) system relates to the use of primary transceivers and secondary transceivers in respective networks that effectuate data transmission. The primary transceivers are coupled with a data source and broadcast or transmit the data source signal to a plurality of secondary transceivers in a local area network. The signal is then transmitted over a long link to another set of secondary transceivers that then pass the signal to another primary transceiver. This another primary transceiver is coupled with the data sink to effectuate signal transmission to the data sink. The data is synchronized in manner that requires minimal processing and does not require closed loop phase control.

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.
