This chapter reviews a recently developed technique for directly measuring the angular velocity of moving objects using a distributed radar aperture with interferometric processing. The use of a distributed interferometric radar provides a direct measurement method for the angular velocity, a quantity which can traditionally only be inferred over multiple measurements.
