  • Patent number: 11280877
    Abstract: The invention relates to a method for testing the electromagnetic compatibility of a radar detector with at least one onboard pulse signal transmitter, wherein said radar detector and each onboard transmitter are part of the same platform, by means of eliminating the external echo component in the signals received by the radar detector, said method comprising a training phase allowing the detected pulses to be divided into classes, grouping together the pulses for which at least two characteristics have a common range of values, and a phase of eliminating the pulses that belong to the selected classes.
    Type: Grant
    Filed: November 10, 2017
    Date of Patent: March 22, 2022
    Assignee: THALES
    Inventors: Daniel Jahan, Jean-Michel Quellec, Jean-Paul Artis, Daniel Christien
  • Patent number: 11181615
    Abstract: The invention relates to a method for testing the electromagnetic compatibility of a radar detector with at least one onboard pulse signal transmitter, wherein said radar detector and each onboard transmitter are part of the same platform, by means of eliminating the onboard component in the signals received by said radar detector, where the onboard component corresponds to the mix of the direct component and the reflected component onboard, said method comprising a training phase allowing the detected pulses to be divided into classes, grouping together the pulses for which at least two characteristics have a common range of values, and a phase of eliminating the pulses that belong to the selected classes.

  • Patent number: 10976401
    Abstract: The invention relates to a method for determining features of an electromagnetic wave received by a reception system (22), the reception system (22) comprising at least two reception channels (13), each reception channel (13) comprising an antenna (21) and a reception chain (14), each reception chain (14) being capable of delivering a value representative of the power delivered by the corresponding antenna (21) after reception of the wave by the reception system (22), the features comprising at least the direction of arrival of the received wave, the method comprising a step of providing a measurement vector, the method further comprising the following steps: comparing the measurement vector to calibration vectors, and determining features of the received wave from the result of the comparison.
