LO Short Course


***Course registration for March 12-14 is now closed. The next course dates are tentatively set for September 24-26 in Dayton, Ohio. To recieve email notifications regarding registration for the next course, email***

ARA's BerrieHill Research Division is excited to offer this professional short course entitled "Fundamentals of Low Observable Technologies." The unclassified teaching materials for this course draw upon decades of inputs from scientists and engineers who were  involved with the development and fielding of LO systems. Previous versions of this course were taught within DoD from 1989 to 2006, and in 2016 The Ohio State University sponsored a significant revision and update to the course materials. In its present form, this professional short course will provide any engineer or scientist a multidisciplinary introduction and history of the development and fielding of Low Observable technologies. There are 19 course segments, including a review of Electromagnetic and radar fundamentals, Radar Cross Section (RCS) concepts, and absorbing materials properties and their measurements. The course also covers other observable signatures (infrared, visual, and acoustic), as well as a comprehensive integration of LO concepts in airframe design. The course culminates in a focused tour of 6-8 relevant air vehicles in the National Museum of the US Air Force. This course is especially relevant to newer engineers who must understand LO technologies if they are involved with designing, producing, flying, or maintaining LO vehicles.
