Ground Astor


Astor; ECM-, TES- and ESM system

ASTOR meets different EW Support- and Threat levels by being adjustable and responsive and fits situations from, basic to advanced EW Training to Tactical Support scenarios.
Astor is in service on L-39, Learjet, MU-2, Sabreliner and in ground-/surface based installations.


System architecture:
The Astor system generates coordinated coherent- and non-coherent jamming techniques. The system has several parallel channels using different characteristics. Operating System is Linux/Ubunto.

Capabilities and Features:
-  Basic to advanced jamming, of single/multiple radars.
-  Mode editor and parameter setting with graphical visualization.
-  DSOR/DRFM and PRI Predictor subsystems
-  Frequency blanking
-  Threat Emitter Simulation
- Logging with GPS-time and GPS-Map
- ESM in each band during jamming and TES.

Characteristics:
Frequency coverage: C- Ka in sub-bands
-  Rx Sensitivity: 65 dBm to - 70 dBm
-  Instantaneous max. Bandwidth,: 2-4+ GHz/band.
-  Dual
12 Bits DSOR/DRFM per band: Pipeline-, Stored Delay-, By-pass-,  Head to tail repeat- and CW modes, main lobe prediction, Fq. blanking, Inverse gain and Look-over- or Look-through functions.
- Jamming modes: Coherent- and Non-coherent Masking-, Deception- and Saturation  techniques. Mode-shifting, Combined- and Synchronized modes and TES.
-  Pulse-,  Phase- and Amplitude Modulation

Adaptive Predictor
The PRI Predictor and four Trackers provides improved performance.
- Records- and stores PRI during jamming
- Identifying e.g. fix, stagger and jitter PRI signals and adapts the behavior to the input signal.
- PRI waterfall display and pulse analyzer display.
- Data base and Library functions

Threat Emitter Simulation, TES:
The Astor can indefinitely reproduce a sequence of arbitrary Pulse Description Words, each specifying:
-  Time of Arrival
-  Pulse Width
-  Pulse Frequency
-  Pulse Amplitude
Intra pulse: Chirp, Phase coding
Arbitrary Scan Modes is simulated with the Technique Generator by reproducing different scan patterns.

Antenna selection and RWR:

By continuously receiving in the Astor Rx antennas, a target direction is provided for each band by a touch display for selecting the right antenna with the same high Rx sensitivity as the Astor. 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.
