Abstract (en)
[origin: EP3522130A1] A method of detecting a moving jamming device issuing a jamming signal, and closing in on an alarm installation, the method comprising the following steps- providing a first signal representative of instantaneous received radio energy;- creating a second signal representative of the average of the first signal taken over a predetermined window;- creating a third signal representative of the time derivative of the second signal;- indicating whether a jammer is closing in based on the third signal
