  • Patent number: 9495595
    Abstract: A method for detecting a stream of electromagnetic pulses emitted, according to a predefined occurrence law, in a scene observed using a detection system comprising a matrix detector and a processing unit for processing signals comprising the electromagnetic pulses. The method includes the following steps: acquiring and transmitting the signals from the matrix detector to the processing unit, and for each pixel of the detector calculating a subtraction signal between two signals acquired during two consecutive time windows of the same length, calculating a signal for accumulating the subtraction signals spaced apart in time by an interval defined by the predefined occurrence law, and thresholding the accumulation signal, the pulse being detected if the accumulation signal is greater than a predetermined threshold for at least one pixel, and locating the pulse detected in the observed scene from the coordinates of the pixel including the detected pulse.
