DEVICE FOR DETECTING PULSED SIGNALS WITH IMPROVED SENSITIVITY

摘要

Device for detecting non-phase-modulated pulsed signals, comprising at least one amplifier (11) receiving a radiofrequency signal, and restoring at least one first signal (RSSI) representative of the envelope of the input signal, and a second normalized signal, characterized in that a module for estimating the stability of the phase (50) comprises means for estimating the phase of the radiofrequency signal, means for evaluating the temporal stability of the phase, the presence of a characteristic pulse being detected if the phase is stable according to determined criteria.
