Jammer Application

0
0

Electronic Countermeasures (ECM) encompass several types of systems, one of which is a jammer. A jammer is a device that emits RF energy to disrupt sensor signals, such as RADAR, or communication signals used by an enemy. Jammer systems range from simple noise emitters, such as barrage jammers, to more sophisticated systems such as deception repeaters. A growing area of interest is the Counter-IED application that jams communication signals used to activate improvised explosive devices (IEDs).

This application note shows how a generic jammer system, a system that can be used to detect, lock onto and jam threat signals emitted by an enemy, can be implemented on its SDR-4902 system.

{tab=SDR-4902 Solution}
The SDR-4902 is an integrated solution that provides the RF and digital processing chain in a two card solution. Configured in a compact desktop air-cooled chassis, the SDR-4902 operates in the 200 MHz to 2.7 GHz frequency range, enable one system to support multiple bands based on your application. The system supports fast frequency hopping waveforms (up to 3000 hops/sec with 10:1 dwell-to-tune time ratio).
