Signal and spectrum monitoring for modern warfare situations

Radio spectrum monitoring for in-theatre force protection

With the rise of ‘network enabled warfare’, wireless communication is playing an increasingly important part of modern warfare. Radio spectrum in any military environment is a scarce resource, and ensuring availability of sufficient radio bandwidth for use by friendly forces, at the same time denying the use of this to hostile forces, is a critical element of in-theatre force protection. Battlefield spectrum monitoring provides military commanders with the essential signals intelligence to detect, analyse and assess threats across a wide geographical area.

CRFS’ solutions address both tactical and strategic needs

Defence applications

CRFS RFeye monitoring and management systems based around distributed networks of intelligent, rugged, low cost, low power RFeye fixed and mobile monitoring nodes, coupled with powerful analysis software, provide an accurate, detailed picture of spectrum usage across a wide geographic area with minimum risk to manpower and machinery.

Nodes may be programmed to autonomously collect data and only transmit when in ‘safe’ locations, or may be used to trigger alarms if specific signals are detected in a local area.

The same concept can be used for border and perimeter monitoring, identifying radio transmissions at the periphery of critical installations or territories which could potentially indicate the presence of hostile forces.

Key features and benefits of CRFS’ approach:

  • Flexible, powerful signal surveillance and analysis using distributed monitoring networks and powerful centralised network management, data management and data analysis tools
  • Interactive control of sub-nets of monitoring nodes for assessment of specific threats
  • Identification and location of illegal or covert transmissions using signal characterisation / demodulation and Direction Finding (AOA & TDOA) options
  • Flexible monitoring network deployment: rugged, low power, low cost RFeye nodes deployable in fixed and mobile monitoring nets. Autonomous operation and intelligent data acquisition.
  • Cost effective battlefield spectrum management
  • Border and perimeter monitoring of critical assets
  • Fingerprinting / background monitoring: 24/7 monitoring of spectrum usage
  • Flexible integration with existing systems
