SkyRadar 61 GHz FMCW Radar

The SkyRadar 61 GHz FMCW Radar extends the SkyRadar modular radar-training system with a modern FMCW measurement source. Mounted on the Radar Box and integrated into the standard SkyRadar data path, it supplies real FMCW measurement data to FreeScopes, where trainees configure, process, visualise and analyse the signals in their own browser-based workspaces.

Designed for universities, technical academies, radar-engineering programmes and laboratories teaching practical FMCW measurement and signal processing.

Training Advantages

  • Work with a Modern 61 GHz FMCW Radar — Use real FMCW measurement data in the SkyRadar modular training environment.
  • Measure Range and Speed — Configure FMCW measurements and analyse distance and velocity.
  • Explore the FMCW Processing Chain — Use the documented FreeScopes FFT 1D block as the range FFT stage, then continue through subsequent supported FreeScopes blocks to observe conversion into range, Doppler and target information.
  • Analyse 3D Target Information — Examine range, speed, azimuth and elevation in the delivered workflow.
  • Compare Processing Approaches — Use the FreeScopes block diagram to compare processing stages and settings.
  • Access Intermediate Data — Analyse data before and after Range-Doppler processing, including Doppler-frequency measurements where supported.

From FMCW Chirps to 3D Target Information

Real FMCW measurements from the radar head enter FreeScopes through the Radar Box and SkyRadar server architecture. In the current implementation, trainees apply the documented FreeScopes FFT 1D block as the range FFT stage, converting the incoming FMCW representation into the range-oriented representation used by the subsequent processing chain.

After this FFT 1D / range-FFT stage, trainees continue through the familiar modular FreeScopes block-diagram workflow used with the NextGen 8 GHz Pulse Radar. They can inspect intermediate data before Range-Doppler processing, perform Doppler-frequency measurements and related signal analysis, then continue to Range-Doppler, detection, raw-target analysis and tracked-target data where included in the delivered configuration.

What Trainees Do

  • Configure FMCW measurement settings
  • Observe real radar measurements in FreeScopes
  • Apply the documented FFT 1D block as the range FFT stage
  • Inspect intermediate data before Range-Doppler processing
  • Perform Doppler-frequency measurements and related signal analysis
  • Continue through supported Range-Doppler and detection stages
  • Inspect raw-target and tracked-target data where included
  • Analyse distance, speed, azimuth and elevation
  • Compare processing settings and resolution trade-offs
  • Repeat controlled experiments in individual browser-based workspaces

Integrated 61 GHz FMCW Radar for Practical Training

The SkyRadar 61 GHz FMCW radar head is mounted on the Radar Box and integrated into the standard SkyRadar training architecture. The Radar Box provides the data path into the SkyRadar server and FreeScopes environment, allowing trainees to work with real FMCW measurements through a modular, browser-based block-diagram workflow.

Where It Fits

61 GHz FMCW radar head → Radar Box → SkyRadar server / FreeScopes → trainee browser

The radar is delivered as part of the SkyRadar modular training system. The Radar Box connects the measurement source to the SkyRadar server and FreeScopes environment, where each trainee works in an individual browser-based workspace. The current 61 GHz FMCW radar replaces the legacy 24 GHz radar in current product messaging and brings real FMCW measurements into the same familiar processing environment used across the NextGen 8 GHz training system.

Prerequisites and Delivery Boundary

  • SkyRadar 61 GHz FMCW Radar integrated with the Radar Box
  • SkyRadar server / FreeScopes environment
  • Suitable targets and controlled experimental geometry
  • Classroom infrastructure according to the delivered configuration

The customer works through the delivered SkyRadar system interface and does not integrate the radar head directly. Available processing blocks and data stages depend on the delivered configuration.

Who It Is For

  • Universities and radar-engineering programmes
  • Technical academies and applied-research laboratories
  • ATSEP and defence radar training organisations
  • Instructors teaching FMCW measurement and signal processing
  • Trainees comparing pulse and FMCW radar principles
  • Laboratories requiring repeatable browser-based radar experiments

Learning Outcomes

After completing the exercises, trainees can configure FMCW measurements, apply the documented FFT 1D block as the range FFT stage, inspect intermediate data, perform Doppler-frequency measurements, continue through supported Range-Doppler and target-processing stages, compare resolution trade-offs, analyse distance, speed, azimuth and elevation, and transfer the experimental method to new controlled scenarios.
