Spectrum Patrol



Scalable RF Collection and Analysis
Locates and Classifies Threats

Spectrum Patrol Performs RF Threat Location Monitoring

The CTL|SystemWare Spectrum Patrol In-Place-Monitoring-System (IPMS) offers the ability to identify internal and external radio frequency (RF) threats, while allowing for differentiation between authorized and unauthorized Personal Electronic Devices operating on common cellular or Industrial, Scientific, and Medical (ISM) radio frequencies. The Spectrum Patrol is comprised of a collection of sensors at a single site, scalable to cover multiple sites with distinct protected areas. The Spectrum Patrol also allows users to complement its capabilities by incorporating additional CTL|SystemWare sensors such as the Raider III, Network Guard and DoubleShot.

Spectrum Patrol System Diagram Example

Spectrum Patrol provides low-level processing, localization through sensor saturation, and the plotting of estimated emitter locations via a 3-D display of the protected area on a Central Monitoring System (CMS). Individual sensors collect, plot and save spectral RF data to networked, internal, or external storage. The sensors compare live data to a dynamic reference file combined with signal source localization to determine alarms. Once a sensor detects an alarm condition, an on-site Central Processing System (CPS) takes readings from all sensors, detecting the potential threat signal. The location data, utilizing GPS if available, of the sensor and signal strength at each point are fed to a localization algorithm which estimates the area location of the transmission source and plots it on a 3D facility display. Once a threat is localized, the nearest sensor provides basic interactive analysis for signal classification, operator examination, and threat determination.
