  • Publication number: 20200256982
    Abstract: A direction finding system and method to utilize synthetic apertures within a single short pulse transmission to extrapolate additional data relating to the signal to thereby increase the accuracy of the direction finding results given by a single short pulse is provided. The direction finding system may further exploit the movement of a platform to create the synthetic apertures within the signal data.

  • Patent number: 10644715
    Abstract: An analog-to-digital converter (ADC) module includes a plurality of frequency stacked ADCs. A splitter splits channels into two segments to transmit the signal through respective low pass and high pass filters to send the analog signal to a low frequency ADC and a high frequency ADC along each channel. When using a quad-tuner having four channels, there are eight ADCs: four high frequency ADCs and four low frequency ADCs. Typically, there is one ADC associated with each channel. Thus, a quad-tuner would be used with an ADC module having four ADCs. However, by splitting and filtering each channel and increasing the number of ADCs in the ADC module, the system, assembly, and method in the present disclosure is able to increase the frequency bandwidth throughput along legacy radio frequency (RF) cables on a platform without the need of replacing any legacy hardware or the legacy RF cables.

  • Patent number: 10644736
    Abstract: An amplifier generate harmonic noise or nuisance signals when the amplifier enters into a nonlinear amplification event. The harmonic noise or nuisance signals are spurious and a tagging circuit may tag them as such so they bypass signal processing logic and provide the same to a downstream hardware device that skips the signals tagged as spurious. The system uses a spurious signal detector and a comparator to identify nonlinear amplification events containing harmonic noise below an amplitude threshold that indicates the harmonic noise or nuisance signals as spurious to the downstream hardware device. Typically, the system is incorporated into an electronic warfare system such that the downstream hardware device effectuates countermeasures for a manned or unmanned platform.

  • Patent number: 9560785
    Abstract: The mezzanine card system and method of use thereof provides a baseboard having opposing sides, each side configured to receive a mezzanine card thereon. A plurality of mezzanine cards are provided having integrated circuits, such as Field Programmable Gate Arrays, fixedly attached thereon. The mezzanine cards of the system reduce reprogramming time from about 15 months to about six weeks. This drastic reduction in reprogramming time provides great advantages for circuitry systems, especially when these systems are used within battlefield and electronic warfare technology. The surfaces of the baseboard are an Electroless Nickel, Electroless Palladium, and Immersion Gold (ENEPIG) plated finish.

  • Patent number: 7548187
    Abstract: In an aircraft-mounted Doppler radar clutter rejection system, a flexible, sharp band pass filter uses Taylor weighting, an FFT and a module for selecting which of the Doppler cells are to be activated, thus to control the band pass characteristic and set the clutter line to the speed of the aircraft.
