There is provided an apparatus for generating a jamming signal for deceiving a transmission/reception device. The apparatus includes a reception unit configured to receive a signal transmitted from the transmission/reception device and a determination unit configured to determine whether or not the received signal is a pulse compression signal. The apparatus further includes a generation unit configured to determine, when the received signal is a pulse compression signal, a deception frequency based on a frequency bandwidth and a pulse width of the received pulse compression signal and generate the jamming signal based on the determined deception frequency.

A synchronous side lobe jamming method for an electronic attack is disclosed. The method includes receiving a radar signal from an external radar; determining the number of synchronous jamming signals based on pulse repetition interval (PRI) characteristic of the received radar signal; generating a synchronous side lobe jamming signal by calculating a generation angle and a generation distance of each of the synchronous jamming signals; and transmitting the generated synchronous side lobe jamming signal to the radar at a predetermined delay time after a jammer receives a side lobe signal.

Methods and apparatuses are provided for estimating a path of an aerial vehicle engaged in attacking network devices in a wireless communication network. A distance function corresponding to the aerial vehicle and a boundary node is determined based on an initial coordinate location of the aerial vehicle and an initial coordinate location of the boundary node. A function of jamming power received at the boundary node from the aerial vehicle is determined based at least on the first distance function and a transmission power of the boundary node. The function of jamming power represents a power associated with a jamming signal received from the aerial vehicle at the boundary node. A trajectory of the aerial vehicle at a plurality of time periods is estimated by the boundary node with an extended Kalman filter. The extended Kalman filter is determined based on the function of jamming power.

A system for providing integrated detection and countermeasures against unmanned aerial vehicles include a detecting element, a location determining element and an interdiction element. The detecting element detects an unmanned aerial vehicle in flight in the region of, or approaching, a property, place, event or very important person. The location determining element determines the exact location of the unmanned aerial vehicle. The interdiction element can either direct the unmanned aerial vehicle away from the property, place, event or very important person in a non-destructive manner, or can cause disable the unmanned aerial vehicle in a destructive manner.
