Compact Range Systems
Compact range reflector-based systems offer users all the advantages of far-field configurations but with the convenience of environmental and security control. The ability to control temperature, eliminate wind deflections, avoid rain and snow as well as reduce maintenance costs are other day-to-day advantages of this product arrangement.
NSI-MI Technologies’ engineers have designed, manufactured and installed more Compact Ranges than all other suppliers combined. A turnkey installation, including chamber, absorber, reflector, positioners and Advanced Microwave Measurement System is a great choice. NSI-MI Technologies’ application engineers can assist customers in defining the appropriate reflector and chamber sizes needed to meet their testing objectives.
Compact range reflector based systems offer users all the advantages of far-field configurations but with the convenience of environmental and security control. For far-field testing of a 3 foot diameter, 10 GHz antenna, the separation distance would need to be nearly 200 feet. A compact range can reduce this distance to under 20 feet. The ability to control temperature, eliminate wind deflections, avoid rain and snow as well as reduce maintenance costs are other advantages of this product arrangement.
The reflector incorporates a prime focus virtual vertex design that places the vertex below the surface of the reflector. This placement reduces multipath and allows for the source feed to be located away from the collimated energy illuminating the test article.
NSI-MI offers standard Compact Range Reflectors with test zone sizes from 1 foot diameter by 1 foot long, to 20 feet diameter and 20 feet long and operational over a wide frequency range. Custom models of different test zone sizes and for high and/or lower frequencies can also be manufactured to meet specific customer requirements.
