The SDR-4902 has an optimized noise figure. This benefits applications with weak incoming signals and low levels of interfering signals. The RF card’s RX adds very little noise to the incoming signal.

Example Applications

• Wideband Datalinks (eg. UAV, UGV, USV)
• Ground Mobile Communications
• Air-to-Ground Communications
• Communications Electronic Warfare (EW)
• SIGINT – COMINT/ELINT
• Satellite Ground Terminals
• Cognitive Radio
• Software Defined Radio (SDR) and Waveform Development

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.
