Planar / Cylindrical Near-Field

Planar / Cylindrical Near-Field

Indoor Ranges

Specifications

Frequency

  • 0.1 - 1.0 GHz (typically)

 

Capabilities

  • Near-field to far-field 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
