Presentation by Tal Oz, Officer, Israeli Air Force.

Many modern radars measure the radial velocity of airborne targets using Doppler shift to distinguish between real targets and clutter (trees, clouds, birds). Radial velocity and Doppler shift are directly related for regular airborne targets such as Boeing 747 but even a standing still helicopter will produce some sort of measurable Doppler shift. It is a computationally difficult task to find the relevant helicopter RCS but a feature provided by Feko, the ""Numerical Green Function"" can dramatically improve computation time of such problems. The lecture will begin with relevant Radar and RCS introduction, some highlights of important Feko features and dynamic RCS results of a CAD model of a helicopter.
