System architecture:
The ITAR free Astor IV multi system is mounted onboard or in two pods and support a wide range of tactical and threat-related EA, TES and ES techniques.
This allows the user to generate traditional threat related jamming techniques as well as modern coherent jamming with coordination and combination techniques.
Unlike many self-protection jammers Astor does not use frequency up- and down- converters; which means it avoids long reaction times with less dynamic range.
To be able to perform all mission profiles Astor use separate generators for each band with dual DRFMs and a SOR, this allows the possibility to work on all bands
simultaneous with fast reaction time in both pipeline- and stored delay modes. Increased Fq coverage is handled by fast µs switching in each band.
Each band is designed with three parallel channels using different characteristics. Each channel can work independently or synchronized to the other channels.

By monopulse amplitude- and phase comparisons the AoA is determined. The RWR alerts the Pilot/EWO of illuminating radar signals from three-four sectors in azimuth.
