The ASTOR III is a modular EW Support System based on the technical/operational experiences from earlier Swedish ECM Systems.
ASTOR III meets different EW Support-, Training- and Threat levels by being adjustable and responsive and fits all situations from, basic to advanced EW Training to Tactical Support scenarious.
Astor III is currently in service on Learjet, MU-2 and ground-/surface based installations and has been certified on L-39E.

Capabilities and Features:

• Basic to advanced jamming, of single/multiple radars, simultaneous on different bands.
• State-of-the-art commercial off-the-shelf technology (COTS) with open source code
• Extensive parameter and mode settings
• Mode editor with graphical visualization usable for teaching, planning and operation
• Digital IFM Set-On Receiver(SOR), Digital Generator -, Optical Adjustable Delay Line(OADL)-, 8 bits Digital RF Memory(DRFM)- and adaptive Predictor subsystems
• Digital frequency blanking filter
• Threat Emitter Simulation (TES)
  
• Logging with synchronized GPS-time and GPS-Map
• Built-in ESM on each band
  

Characteristics:

• Frequency coverage: 0.4 –20 GHz (optional Ka-band) in sub-bands.

• Rx Sensitivity: – 65 dBm to - 70 dBm

• Instantaneous maximum bandwidths: SOR/DRFM: 2 GHz, OADL: 6 GHz.

• Jamming modes: Coherent and Non-coherent Masking-, Deception- and Saturation techniques. Mode-shifting in time, Combined and Synchronized modes.

• SOR: Digital direct Fq. discriminator and WB DLVA techniques. Fq. blanking filter, main lobe prediction, inverse gain, look-over and look-through functions and TES.

• DRFM: FPGA based, 8 Bits. Pipeline-, Stored delay-, By-pass-, Head to tail repeat- and CW modes. Main lobe prediction, Inverse gain and Look-over function.

• OADL: Coherent Optical Adjustable Delay Line for e.g. leading edge jamming, RGPO and Cover-pulse, stand alone or in combination with SOR/DRFM

Adaptive Tracker and Predictor provides improved Techniques generator performance:

• Requires no emitter parameter input/library data
• PRI tracking and prediction
  
• Identifying e.g. fix, stagger and jitter signals
• Adapts behavior to the input signal characteristics
• Built-in robustness against spurious and missing pulses

Operating System: Linux, UNIX, Free BSD and optional Windows

Threath Emitter Simulation, TES:

The Astor III SOR generator can as stand alone or incorporated in the Astor III generator be programmed to indefinitely reproduce a sequence of arbitrary Pulse Description Words, each specifying:

• Time of Arrival (TOA)
• Pulse Width (PW)
• Pulse Frequency (FQ)
• Pulse Amplitude (AMPL)

Features:

• Frequency: I/J- and J-band, resolution 1 MHz

• Stable, sweep, bursts, random agility, user defined.

• PRF: 200 - 5000 000 pps

• PW: 0.1 - 51 micro sec.

• # of pulses in a frame: Up to 4096

• Patterns: Fixed, dwell- and switch, stagger, jittered

• Ant. scan: Circ, Az. sector- or off center, measured lobe patterns.
• User defined antenna pattern, 360 degrees
  

• Period time: 0 - 60 000 ms
• Pre-programable-, cascading scenarios
  

Optional:
Digital Com Jam and COTS RWR.
