Electronic support measures and self protection
Radio Frequency (RF) receivers
High-precision phase-difference interferometric Direction-Finding (DF) techniques are used with digital FFT*-based channelised receivers for high sensitivity and long detection range and selectivity in dense scenarios.
Full-azimuth instantaneous coverage by quadrant receivers using amplitude-monopulse-based direction finding.
High-performance wide-band receivers for close to 100 % probability of intercept and high instantaneous dynamic range.
Narrow-band receivers offer good detection range and resolve high-density signal environments while adaptive search programmes optimise performance.
*Fast Fourier Transform
Advanced and well-proven, high confidence, automatic emitter-identification algorithms based on a fully user-programmable library.
Direction finding and emitter location
Position is estimated for every ground-based track by the emitter location function.
Pulse and intrapulse data from intercepted signals can be displayed in real time displays and captured as formatted Pulse-Descriptor Words (PDW) and Intrapulse Descriptor Words (IDW) for off-line analysis.
Extensive recording capabilities that can either be initiated manually, or automatically controlled by events in combination with library data.
Human-machine interface (HMI)
The ESM system has a user-friendly, Windows-based graphical user interface with situational-awareness display, including a geographical map, and real-time monitoring and analysis capabilities.
Self-protection system (SPS)
The sensor range includes radar warning, laser warning and missile-approach warning and provides established tracks to the defensive-aids controller for evaluation. The defensive-aids controller provides the selection and initiation in auto modes of chaff/flare countermeasures sequences based on the weapon system data from the threat library. In manual mode, the pilot can select countermeasure programmes and initiate dispensing using the cockpit controls.
Electronic Warfare (EW) support
Saab offers an EW support system to meet the extremely demanding needs of EW organisations performing analysis of electronic-warfare data and the reprogramming of threat-and-countermeasures libraries.
It significantly reduces the time needed for the reprogramming of threat libraries and analysis of recorded EW data, thereby enhancing crew survivability and the likelihood of mission success.
For operational support in EW matters, we offer EW Operational Support (EWOS).
