Patent number: 11041947Abstract: A method and system for identifying an object in one space monitored by at least one radar transceiver. The method comprises storing intervals of critical distance values (10) associated with the position of a fixed object upon which a time-varying radio signal shadow may be generated, which may be confused with a moving object. Through successive radar detections, the signals are processed and generate a measurement range profile (40), from which a background range profile (41) is extracted to obtain an object range profile (50). The distance of a possible detected object (60) is determined from the analysis of the object range profile. If the distance of the object (4) is external to the critical intervals (51), the object is classified as valid (55). If the distance is internal to the intervals, the detected object may be a shadow and unless further checks are performed, its presence is not indicated.Type: GrantFiled: October 5, 2018Date of Patent: June 22, 2021Assignee: INXPECT S.P.A.Inventors: Alessio Degani, Andrea Tartaro

Patent number: 10587359Abstract: A method and system of reliably detecting a reactive jamming attack and estimating the jammer's listening interval for exploitation by a communication system comprises channelizing one or more signals of interest (SOI), channelizing one or more signals of unknown origin (SUO), identifying frequency support patterns for the SOI and SUO using Bayes thresholds, comparing SOI and SUO detection map histories, and determining a percent match, where a match percentage above a specified minimum indicates a reactive attack. Edge detection can be used to enhance jammer support. Embodiments further detect reactive jammer adaptation to changes in the SOI's frequency support. Embodiments include detectors that are insensitive to jammer modulation and/or signal type. A jammer reaction delay and/or size and periodicity of receive window can be detected. Embodiments determine if a jammer is copying and retransmitting the SOI's waveform(s), and/or if the jammer is anticipatory.Type: GrantFiled: November 16, 2016Date of Patent: March 10, 2020Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Matthew C Bromberg, Dianne E Egnor
