A Portable Anechoic Chamber for PAD Use

The design and construction of a small light-weight anechoic chamber for testing the first orbiting rendezvous radar on a launching pad are described. Performance and weight considerations were evaluated and a practical compromise was reached. A chamber capable of measuring L-band radar angular accuracy and weighing only slightly more than 100 pounds was the result. Radar RF go, no-go checks can now be performed on the launching pad or in other locations with a low cost device.
