This presentation will communicate new methods to measure the physical dimensions of structures of rotating objects observed by radar systems. Using a pure CW waveform, it is possible to dimension structures that are rotating in the Doppler dimension by exploiting Micro-doppler cyclic signal processing methods that allow for the replacement of absolute time with the relative periodicity of a rigid body rotating structure across a fixed axis. The formulaic breakdown is given to determine a rotating object’s rotation rate, main body diameter, fin/stabilizer lengths, and the number of fins/scatterers on a rigid body with high precision that is not dependent on the range resolution of the radar. An example that shows dimension determination using live data from an artillery round and a terrier-sounding rocket will be provided and discussed.
