The Astor IV TG contains a receiver and three parallel jamming channels: two wideband DRFMs and one wideband SOR. This creates the ability to combine obscuration jamming and deception jamming. The techniques, that are fully user programmable, are:
- Barrage noise
- Spot noise
- Spot noise with frequency memory
- Pulsed noise
- RGPO/I, VGPO/I
- Cover pulse with or without accelerating edges
- False targets
- DRFM CW
- Multiple false targets
- Pattern projection (project a picture in the radar)
- TETRIS (special high density false target technique)
- Asynchronous pulse train
In addition, amplitude modulation (AM) can be applied to any technique and phase/frequency modulation can be applied to any DRFM technique.
The AM techniques are:
- Constant gain
- Constant gain with delay
- Inverse gain
- Square wave/swept square wave
- Sawtooth/swept sawtooth
- Sine/random sine
- Count down
The phase/frequency modulations are:
- Frequency sweep
- Random frequency modulation
- Coordinated doppler (coordinated with false target range motion)
- Phase noise and binary phase noise
- Binary phase shift keying
- XRN (special alternating sideband modulation)
Jamming techniques can be scheduled in time to create jamming sequences.
The System contains a PRI tracker that can identify fix and dwell & switch, stagger, sliding and jitter PRI. The primary purpose of the tracker is to support the generation of up-range false targets even if the radar uses agile PRI.
All user data (jamming techniques and log files) are stored on a USB key and the system contains no user data after power down.
The System can also perform threat emitter simulation (TES) with a pre-programmed arbitrary waveform.
The HMI have an extensive mode editor with animations of the programmed technique. The receiver data are presented in a waterfall display. In addition there is an oscilloscope showing detector signal, frequency signal and transmitted signal and PRI waterfall.
