Radar Cross Section (RCS) Solutions

Solutions pour la mesure de la section transversale des radars

400 MHz - 18000 MHz

MVG fournit des solutions complètes de mesure RCS, de l'acquisition des données au post-traitement, dans des gammes de tests telles que :

Intérieur : Chambre conique, générateur d'ondes planes (PWG), gamme compacte (CR), et planaire/cylindrique proche.
à l'extérieur : Champ lointain (FF), champ proche planaire et cylindrique (NF)

Nos systèmes clés en main entièrement intégrés sont conçus et construits en interne pour garantir une grande précision, des performances au niveau du système et une intégration transparente avec des besoins d'essais en constante évolution.

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
