RF Communications Jamming

 Achieve optimum communications jamming with RF record and playback

In all areas of military conflict the ability to jam remote detonation signals for explo­sive devices is critical in order to protect military and civilian personnel and equip­ment. However, this jamming has to be achieved in a way that does not compromise the integrity of military communications, radio sensing and GPS navigation systems.

The development of effective jamming solutions requires the analysis of the complex RF environment that exists when multiple communications systems are in use. Only by analyzing the RF environment in detail can the correct decisions be made on the required signal-to-noise ratio, the optimum waveforms to use and the mechanisms by which the detonation signal can be jammed. This detailed analysis requires the recording of RF information and spectral activity, in the field, over an extended period of time.

An integrated RF record/playback solution from Keysight Technologies and Bird al­lows the long-term record and storage of RF data for later playback and analysis. The solution comprises a Keysight N9040B UXA spectrum analyzer together with a Bird IQC5255B dual-channel, long duration signal capture and playback system. Together, these provide a unique approach to the challenge of recording, analyzing and creat­ing new waveforms in complex RF environments.

The Keysight N9040B UXA spectrum analyzer has 255 MHz of acquisition bandwidth with 78 dB of spurious free dynamic range to 50 GHz. The analyzer provides the bandwidth, dynamic range and frequency coverage to record jam­ming signals in even the most cluttered and contested RF environments. The Bird IQC5255B signal record and playback system is a portable, dual-channel sys­tem that allows you to record/playback uninterrupted data streams and event markers for up to a day, depending upon the acquisition bandwidth selected.

The IQC5000B also includes I & Q analog outputs so it can re-play all or any part of the recorded spectrum with full 16 bit I and Q precision using a Keysight vector signal generator. These capabilities make it possible to find critical signals of interest from within the record data rapidly.

With an RF record/playback solution from Keysight and Bird you can record and ana­lyze the components of a complex RF environment over a long period of time allowing you to achieve optimum communications jamming for maximum effect
