Abstract
Cutting-edge technology historically stems from military applications and needs. This remains true for communication and tracking antennas. Since 1957, Ball Aerospace has led the frontier for once-thought-impossible antenna designs and capabilities, currently outfitting the F35 Lightening II, Hubble Space Telescope, New horizons, and many, many more.  To prove that these antennas work they must be tested and validated in state-of-the art anechoic chambers. Ball aerospace runs and operates five unique chambers that have specialized designs and frequency ranges and together they provide broadband measurement capability suited for all types of antennas with all kinds of purposes. This seminar will discuss how to take Low Observable antenna gain / radar cross section measurements inside compact and tapered anechoic chambers with information including, but not limited to ISAR imaging, vector subtraction, basis pursuit functions, near-field corrections, antenna gain measurements in 1D, 2D, and 3D, controlling SNR and uncertainty in measurements, and what the future holds for antennas development.

Bio. 
James (Jamie) Bittle completed his Master of Science in Electrical Engineering degree at the University of Colorado Denver where he worked as a research assistant under advisement from Dr. Golkowski on very low frequency electromagnetic related projects (remote sensing, transmission, imaging, LWPC modeling). Since graduation, he took the position as the responsible RF engineer for the compact anechoic range at Ball Aerospace where many programs (developmental and production) test, experiment, and validate the functionality of low observable antennas for land, air, and space crafts.
