Different antenna height configurations, depending on target distance and frequency allows better ground bounce control

Clutter Control

Different possible radar fence configurations for reduce ground bounce effect

Control Room

Can be facilitated as fixed ground station or mobile down range vehicle

Planar and Cylindrical Near-Field

Outdoor Ranges

Specifications

Frequency

0.4 - 18 GHz (typically)

Target

Full-scale target measurement at short distances
Applicable to both model and real targets – as - is / before take-off

Planar / Cylindrical Near-Field

Indoor Ranges

Specifications

Frequency

1.0 - 40.0 GHz (typically)

Capabilities

NF to FF correction in the ISAR software tool allows focalization of the radar image
Effectively mitigate clutter through advanced data processing techniques and high-resolution capabilities

Compact Test Environment

NF RCS ranges require much less physical space than traditional far-field ranges, making them ideal for indoor labs, production environments, or urban locations

Cost Efficiency

By avoiding long distances needed in far-field setups, NF RCS ranges reduce infrastructure and operational costs

Enhanced Measurement Flexibility

The test setup allows for multi-angle and multi-polarization scanning, and can handle complex test scenarios

SAR and ISAR Imaging Capabilities

NF RCS systems can generate SAR (Synthetic Aperture Radar) and ISAR (Inverse Synthetic Aperture Radar) images, providing high-resolution radar imagery of static or moving targets
- SAR allows imaging by virtually moving the radar around a stationary target
- ISAR captures images of a moving target using its motion to synthesize the aperture.These capabilities are invaluable for feature identification, scattering analysis, and target classification
