Abstract
A method for determining spin of a projectile is disclosed that includes generating an electromagnetic radar signal and transmitting the electromagnetic radar signal towards a projectile, receiving a reflected electromagnetic radar signal from the projectile and transforming the reflected electromagnetic radar signal from a time domain to a frequency domain to generate a frequency domain signal. A peak frequency component of the frequency domain signal is identified, shoulder frequencies adjacent to the peak frequency component in the frequency domain signal are identified, and an estimate of the spin of the projectile as a function of the shoulder frequencies is generated.
