Deploy Quicker, Produce Faster
• Increase the probability of intercept for off-the-air RF signals
• Re-configure signal detection without programming to increase probability of intercept
• Quickly categorize and select target signals using visual, audible, and analytic tools
• Improve mission productivity by automating common processing tasks and mission setups
• Complete solutions to support tactical operations including demodulation and decoding of device-specific signals
• Increase interoperability and re-use through integration with legacy systems and open programming capability
• Scalable performance from simple survey solutions to completely integrated intercept and collection solutions
• Rapidly deployable solution based upon industry-standard off-the-shelf components
The tools you require depend on the amount of knowledge you have about the target. The E3238S/35688E supports missions from the simple, such as cataloging the signal environment, to the complex such as interception and collection of information from specific devices and users.
Survey
Initially, the operator must survey RF spectrum for signal energy. Since the number and variety of signals is so large, and the spectrum so vast, efficiency is critical. The hardware must be able to search for new signals as they appear, and the operator must have the tools to quickly determine the kinds of signals that are present.
Collection
Once the types of signals of interest are known, a system can be put in place to collect them, usually by recording them for later analysis. To increase mission efficiency, the system must be able to differentiate between modulation types, and collect signals of the target types only. Even then, the task of sorting through the recorded signals can be time consuming. Analysts may need to determine how to demodulate the signals, or linguists may need to listen to each signal to determine if it is important. The goal is to rapidly identify the specific devices and users so that no critical signal will be missed.
Universal signal detection
The universal signal detection option spans both survey and collection. A universal signal detector automatically identifies signals of interest by operating on the characteristics of RF transmissions. Agilent’s universal signal detection (Option USD) includes bandwidth filters, frequency plans, wideband detectors, and narrowband
confirmers. These wideband and narrowband technologies are combined to efficiently sift through the crowded spectrum and significantly increase the probability of intercept. As signals of interest are detected, simultaneous gap-free recordings (or data streams) are easily handled by
the multiple digital down converters (DDC) and parallel DSPs in the E3238S system. When a new threat emerges you can quickly build a detector from a recording of a new signal without programming.
Device-specific applications
Once specific devices have been identified, and critical identifying information such as pager capcodes, phone numbers, and communication frequencies and times have been extracted, then device-specific demodulators and decoders can be put in place to capture signals of interest as they occur. For data transmissions, the message content can be put in a searchable database, real-time searches can be performed and reports generated. For voice transmissions, operators can listen to the communications as they occur to
support tactical operations.
