摘要：
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.
