Patent number: 10371795Abstract: A radar warning receiver is disclosed. The radar warning receiver includes an antenna, a signal detection unit, a signal identification unit and an alarm. The antenna collects radio frequency (RF) signals. The signal detection unit is configured to generate a group of frequency and amplitude signals based on the collected RF signals. Specifically, the signal detection unit includes a pair of limiting amplifiers for converting the collected RF signals into corresponding pulsed output signals that track the actual frequency oscillations of the collected RF signals, and a pseudo-random noise generator for injecting noise into one of the limiting amplifiers. Based on the frequency and amplitude signals, the signal identification unit determines whether or not any of the collected RF signals includes a threat signal. The alarm is utilized to present a threat signal to a human operator.Type: GrantFiled: February 6, 2017Date of Patent: August 6, 2019Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: James M. Huggett, Kevin S. Bassett

Patent number: 10367243Abstract: Low temperature co-fired ceramic (LTCC)-coupled stripline resonator filters for use as bandpass filters are implemented with combline topology or with interdigital topology. The filter bandwidths range from about 0.3 GHz to less than 1 GHz with frequency operation of about 0.1 GHz to 100 GHz. The filters have vias between adjacent resonators with via spacing significantly smaller than the wavelength at the filter center frequency to generate electrical walls between adjacent resonators resulting in coupling reduction for narrowband filter implementation. A narrowband filter transformer loading structure launches the input and the output to the first and last resonators.Type: GrantFiled: May 2, 2017Date of Patent: July 30, 2019Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Souleymane Gnanou, James M.

Publication number: 20180323485Abstract: LTCC coupled stripline resonator filters for use as bandpass filters are implemented with combline topology or with interdigital topology. The filter bandwidths range from about 0.3 GHz to about 4.5 GHz, or higher, depending of the manufacturing limitations with frequency operation of about 0.1 GHz to about 100 GHz. The filters have a plurality of through plated vias extending through the filters and connecting the top and bottom ground layers to form electric walls thereby reducing the coupling between the adjacent resonators.Type: ApplicationFiled: May 2, 2017Publication date: November 8, 2018Inventors: Souleymane GNANOU, James M.

Patent number: 8660671Abstract: What is provided is a receiver-on-a-chip comprising a monolithic integrated circuit that reduces the receiver to a cigarette-pack-sized assembly mountable directly at an antenna element, with a much-increased operational bandwidth and instantaneous bandwidth, increased dynamic range and with a two-order-of-magnitude decrease in size and weight. Moreover, because of the elimination of all of the I/O drivers and attendant circuitry, power consumption is reduced by two-thirds, whereas the mean time before failure is increased to 10,000 hours due to the robustness of the monolithic integrated circuit and use of fiber optics.Type: GrantFiled: April 20, 2012Date of Patent: February 25, 2014Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Frank D. Stroili, James M. Huggett

Patent number: 8138969Abstract: A radar warning receiver is implemented in low cost integrated circuit form utilizing only one analog component, namely a limiting amplifier. By taking the output of the limiting amplifier and utilizing monobit sampling of the output it has been found that one can provide an integrated circuit single chip radar warning receiver using delay correlation to extract frequency, amplitude and modulation type from signals at or below the noise level.Type: GrantFiled: October 1, 2009Date of Patent: March 20, 2012Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: James M.

Patent number: 7236901Abstract: The present invention relates to a device and method that digitally replicates the analog processing that is normally associated with an instantaneous frequency measurement device. Specifically, the present relates to a digital frequency measurement device comprising: a filter, where the filter receives an input RF signal and transmits an output signal centered around a desired frequency; a limiting amplifier downstream of the filter, where the amplifier receives and amplifies the output signal; a deserializer downstream of the amplifier that continuously samples the output signal from the limiting amplifier; and a digital frequency measurement processor (DFM), where the DFM receives data at a rate of 1/16 of the deserializer sample rate. The DFM transforms the data into multiples stages that are combined in order to produce an estimate of the input signal, where the DFM is implemented through a digital processing device.Type: GrantFiled: May 14, 2004Date of Patent: June 26, 2007Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventor: James M.
