Characteristics and Functions of Electromagnetic Spectrum Monitoring

2022-05-23

I. Overview of Electromagnetic Spectrum Monitoring

  1. The targets generally cover all radiation sources within the spatial scope, including hostile (illegal), friendly, neutral and natural radiation sources. The primary tasks of monitoring are to detect and measure the characteristics of these radiation sources, such as their temporal attributes, spatial parameters (direction), spectrum, polarization, modulation mode, modulation parameters, power and friend-or-foe identification. Beyond providing an understanding of the electromagnetic situation and supervising the rationality and legality of spectrum utilization, the monitoring results also enable the effective utilization, management and control of spectrum-dependent systems, as well as the timely avoidance of various electromagnetic conflicts and mutual interference.

  2. It constitutes a key component of electronic warfare and information warfare, giving rise to a wide array of electromagnetic combat operations. Electromagnetic signals can be categorized into two types based on their temporal characteristics: continuous signals and pulse signals.

  3. The former have a relatively long duration, with their spatial, spectral and modulation characteristics remaining stable or changing slowly. The latter have a short duration, and their temporal and spectral modulation characteristics are not only variable, but also subject to significant and rapid changes.

  4. Traditional electromagnetic monitoring has focused more on continuous signals, adopting a combination of spatial and spectral scanning and dwell time. Its capability to monitor pulse signals is limited.

II. Characteristics and Functions of Electromagnetic Spectrum Monitoring

  1. Portable-grade security protection, with dustproof, anti-collision and waterproof features.
  2. Supports full remote real-time control of the equipment from any location.
  3. Remote real-time spectrum display and data storage.
  4. Allows for multi-point monitoring.
  5. Ultra-high signal sensitivity.
  6. Full-frequency seamless monitoring achieved through multi-antenna configuration.
  7. Radio monitoring for communications intelligence (COMINT) and electronic intelligence (ELINT).
  8. Mobile radio spectrum monitoring for security operations and major events.
  9. Radio interference monitoring and identification in key areas (airports, ports, border regions, classified facilities).
