ABSTRACT:
A jammer includes means for receiving a local radio transmission and means for determining the frequency of the local radio transmission. Monitoring circuits are arranged to detect the end of the local radio transmission and only then to trigger the transmission of a jamming signal by jamming signal transmitting means. In this manner the jammer jams local reception of the response of a non-local station to the detected local transmission. The jammer is able to jam effectively using a low power signal. The reduction in the power-consumption of the jammer makes it particularly suitable for use as a leave-behind jammer for military applications.
