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
