Publication number: 20220303622Abstract: An apparatus for passive coherent location includes a forecaster, an evaluator, a receiver, and a correlator. The forecaster generates a prediction of a radio-frequency signal transmitted from an antenna of a broadcasting service. The evaluator generates an effectiveness metric from the prediction of the radio-frequency signal. The receiver receives the radio-frequency signal that an object reflects from the antenna to the receiver. The correlator determines, from the radio-frequency signal reflected from the object as received at the receiver, an ambiguity function having a maximum at a temporal offset and a Doppler shift. The temporal offset and the Doppler shift at the maximum partially determine at least a position of the object. The apparatus optionally includes a selector for tuning the receiver to the radio-frequency signal in response to the effectiveness metric.Type: ApplicationFiled: March 19, 2021Publication date: September 22, 2022Inventors: Gregory Knowles Fleizach, Nicholas T. Johnson, Mohamed Chergui, Christopher Lichtenberg, Michael P. Civerolo

Patent number: 10921423Abstract: A radar pulse generator includes a multiplexer, a polyphase synthesizer, a first signal channel and a second signal channel. The multiplexer has a baseband radar pulse input, a multiplexer control input, a first channel output and a second channel output. The baseband radar pulse input signal is a single channel baseband radar pulse signal. The multiplexer control input signal selects one of the group consisting of the first channel output and the second channel output. The polyphase synthesizer synthesizes the first channel output signal, synthesizes the second channel output signal and outputs a desired radar pulse signal based on the synthesized first channel output signal and the synthesized second channel output signal. The first signal channel provides the first channel output signal from the first channel output to the polyphase synthesizer. The second signal channel provides the second channel output signal from the second channel output to the polyphase synthesizer.Type: GrantFiled: July 25, 2018Date of Patent: February 16, 2021Assignee: United States of America as Represented by the Secretary of the NavyInventors: Michael P. Civerolo, Nicholas T. Johnson, Nicholas A. Lumsden, Colin J. O'Brien

Patent number: 10620292Abstract: A signal evaluation system is provided for evaluating a first EM signal and a second EM signal for use in a passive coherent location system. The signal evaluation system includes: a spectrum detecting component that detects the first EM signal and the second EM signal; a signal characterization component that generates a first characterization of the first EM signal and to generate a second characterization of the second EM signal; and a ranking component that ranks the EM signals for use in the passive coherent location system. The first characterization is based on an amplitude associated with the first EM signal and one of range resolution, Doppler resolution, and combinations thereof associated with the first EM signal. The second characterization is based on an amplitude associated with the second EM signal and one of range resolution, Doppler resolution, and combinations thereof associated with the second EM signal.Type: GrantFiled: September 6, 2017Date of Patent: April 14, 2020Assignee: United States of America as represented by Secretary of the NavyInventors: Nicholas T. Johnson, Mohammed Chergui, John D. Rockway, Oren Sternberg

Patent number: 9923741Abstract: A signal detection method that allows characterization of a modulated signal to be efficiently determined. The method comprises the steps of receiving a data signal, processing the data signal to determine its value squaring the value of the signal; filtering the squared signal value to remove DC content; evaluating the resulting signal to determine if a single sinusoidal value remains; and determining that the presence of a single sinusoidal value as the resulting signal from the squaring and filtering steps indicates that the received data signal is a phase-shift key signal or conversely that the absence of such after a given number of cycle of squaring and filtering indicates a different modulation technique is present in the signal.Type: GrantFiled: March 24, 2017Date of Patent: March 20, 2018Assignee: The United States of America as represented by Secretary of the NavyInventors: Michael P.
