Sirius Surveillance - C-ESM and R-ESM

Key features

High degree of automation up to fully automatic
Networked sensors
Integration on any platform or fixed installation

Superior communication surveillance

Exploiting the explosion of communication in the electromagnetic domain, Saab’s Communication Intelligence (COMINT) and Communications Electronic Support Measures (C-ESM) sensors find the right balance between automated and operator-controlled surveillance.

This enables surveillance using networked automated sensors on any platform or fixed installation.

Automated analysis of the radio theatre

The goal is to obtain a picture of the complete radio spectrum. All signals in the requested band are detected, geo-located, classified, demodulated and decoded. Wherever possible, these tasks are performed automatically. Detailed mission planning guarantees that the important signals of interest are detected and processed. The results are demodulated signal recordings and reports for each signal, stored in a centralised database.

Emitter geo-location in urban scenarios

The semi-mobile and mobile geo-location of (mobile) emitters with our sensors in urban or hilly scenarios support security at large-scale events, such as major sports events like the Olympic Games or other large public gatherings. It also supports the search for illegal operation of communication transmitters, such as unauthorised Very-Small-Aperture Terminals (VSAT).

Situational awareness of the surroundings

Our sensor systems provide supporting information to the situational picture, using the analysis of signals from a certain area. After an analysis of the situation, an automatic warning function provides threat or abnormality-detection information.

Detection of fake emissions

Saab’s COMINT technology can be used to detect of fake emissions, i.e.; a difference in the sent signal and the real identity and position of vessels and aircraft. Comparing the position information from a direction finding with the one reported in the signal exposes the fake information, which triggers the warning function, for example the *AIS or *ADS-B signals.

*AIS: Automatic Identification System
*ADS-B: Automatic Dependent Surveillance–Broadcast

Land, naval and air communication

Amplitude Modulation (AM), Frequency Modulation (FM) and digital communications signals are detected, processed and recorded from the civil and military domains, covering naval, air and land communication. All signals can be recorded and processed automatically.

Detecting and analysing Unidentified (UI) signals

Our solutions detect the signals that are new to the current radio theatre and the system displays which signals that have not been processed, using standard means. These unidentified signals are stored in a database and can be analysed for technical and tactical information.

Did you know...

… that although everybody speaks about 5G, High-Frequency (HF) communication is more in-use than ever before? This is because HF is the only medium for worldwide coverage.

  • Our sensors integrate seamlessly with the SIRIUS sensor product family providing a true SIGINT and ESM functionality.
  • Adaptive digital beamforming allows you to improve monitoring simultaneously for several thousands of channels in paralell. Our algorithm creates a beam pattern for each individual interception, suppresses interferers and helps to overcome fading effects. Thus, largely improving the quality of the monitoring results.
  • Our new resource management splits signal detection and signal production. This enables the signal production resources to be freely and dynamically allocated to multiple sensors, e.g. covering different frequency ranges for monitoring.
10,000 signal production channels are possible within our COMINT sensors
