HRRPs-based target length estimation using a FMCW radar

This paper proposes a filtering method to estimate the length of a moving target tracked by a frequency modulated continuous wave (FMCW) radar. The method generates high resolution range profiles (HRRPs) from the radar echo signal and then integrates them into an extended Kalman filter (EKF) to simultaneously estimate the target motion and geometry. Numerical simulations on tracking a ballistic target represented by one-dimensional scattering centers verify the effectiveness of the proposed length estimation methodology.
