LRAD Microstrip Antenna Array

This shows the array being tested by Jim Bertram at the Goddard Automated Antenna Measurement System (GAAMS), Bldg. 19, NASA Goddard Space Flight Center, Greenbelt, MD., in May 2002. This part of the GAAMS facility is a tapered anechoic chamber, which can make accurate measurements at L-band. The 64-element array face is covered by a temporary foam board strapped to the strongback structure.
