Each compact range reflector is made to exacting standards for optimum illumination and uniformity. The reflector’s main body is the structural back bone of the composite assembly and provides the structural integrity. The serrated or rolled edges are fabricated of lightweight materials that serve to provide structural integrity for themselves, not the overall composite assembly, thus significantly reducing the unit’s weight. All reflectors have a life expectancy exceeding 20 years.


  • High stiffness to weight ratio

  • Focal lengths from 1 m (3 ft) to 11 m (36 ft)
  • Achievable frequency range of 1-200 GHz
  • Serrated edge or rolled edge available
  • Modular design is easily configured to unique specifications

Frequency 1 – 200 GHz
Focal Length 1 – 11 m (3 – 36 ft)
Amplitude Taper 1
Amplitude Ripple ± 0.5 dB
Phase Variation (<18 GHz) ±5°

The CRR Family of Compact Range Reflectors offers three feed layouts - center fed, corner fed and side fed - to allow the most flexibility for your test range design. The primary difference in reflector geometries is for these feed layouts. There are both advantages and disadvantages for each feed placement. They relate to electromagnetic performance, range use and the ability to optimize a reflector to an existing facility.

All of our standard compact range reflectors offerings have serrated edge treatments. Models with rolled-edge treatments and custom models are also available. Typical customizations include specially sized reflectors or edge treatments to address specific electromagnetic requirements. For example NSI-MI-Technologies has built dual reflector compact range systems, portable compact ranges and other creative solutions to meet customer requirements. Compact ranges with quiet zones up to 11.58 m (38 ft) wide have been delivered by NSI-MI’s experienced engineering and manufacturing teams.
