SkySim Radar Simulator incl. Virtual Jammers -  Description & Datasheet

print-icon

The simulator is able to simulate radar, noise jammer and deception jammers. This allows to apply the simulator in the context of civil and military defence training. The signals can be superimposed on the live raw data stream of SkyRadar's NextGen 8 GHz Pulse radar and thus create a realistic training context of multiple jamming scenarios.

The solution allows for the following scenarios

  • Full simulation (radar and jammer are simulated)
  • Real radar and real jammer

POSSIBLE EXERCISES

The scope of exercises in the fields which can be implemented with the DSP radar simulator is virtually unlimited. So we just state some fields of application here:

Radar Operation Skills
(FreeScopes series Basic and ATC  required)

  • Radar modes pulse, pulse compression, Doppler, FMCW
  • Variation of transmission power, frequency, pulse width, antenna elevation, antenna rotation speed
  • Application of algorithms and filters like STC, Source Suppress, CFAR, FFT, MTI, MTD etc.

Defense against Disturbances and Jamming Attacks
(FreeScopes series ATC Disturbance Filtering and Analysis required)

  • Defense strategies against noise jamming

Radar Model

The simulator is based on a simulated radar model with parameters like

  • Detection probability 
  • False alarm rate
  • Range 
  • Range resolution
  • And for the targets:
    Target RCS

Modulation & Waveform

  • Rectangular pulses (variable)
  • PRF (variable)
  • Pulse width (variable)

Noise

  • Artificial Jamming (Noise)

Transmitter

  • Stimulated emission power is based on the required Signal-to-Noise ratio SNR
  • SNR is a function of Pd, Pfa and pulse integration
  • Ptx (minimum value) calculated from the Radar equation

Antennas

  • Radiator Tx for Radar and Jammer
  • Collector Rx for Radar and Jammer

Simulation


  • Static and moving targets in the simulation environment
  • Spectrogram of Simulated WaveForms

Propagation Environment

Propagation channel between radar and target

  • Sampling Rate
  • WavePropagation
  • Operating frequency

Simulator Output

The simulator provides JSON-formatted I&Q data as output. It is enhanced with metadata like time-stamps.

It can be directly used in FreeScopes or passed to analytic environments like MATLAB with SkyRadar's SDK

Signal Processing

Signal Processing is done in FreeScopes, based on

  • IQ Data
  • Power Detection

Jamming

The jammers in the simulated jamming environment are able to match the following radar characterstics:

  • operating frequency
  • pulse repetition frequency (PRF)
  • pulse repetition interval (PRI)
  • pulse width

The simulator for Jammers makes use of the Radar Model. It can emulate Noise Jammers and Deception Jammers.

Noise Jammers

  • barrage jamming
  • spot jamming

Deception Jammers

  • repeater jamming
  • range deception jamming

The supply of the jamming add-on is subject to EU regulation. This is not an attack simulator and it does not train jammer attacks. It trains security protection and defense as required in context of malicious and accidental disturbances for civil and military aviation infrastructures.

  • FreeScopes ATC Disturbance Filtering & Analysis II

Teacher Panel

The teacher panels allows to set the simulator. He / she can place the targets, define the radar type, elevation angle, range, range resolution, Gain and more.

When purchasing simulator and jammer, the panel also allows to set the jammer.
