On Doppler measurements for tracking
Matthew A. Smith · 2008
This paper provides an investigation of the fundamental and practical distinctions between state estimates obtained by using the positional components of a phased array radar (PAR) measurements versus the estimate obtained by using the additional Doppler component. By employing the Doppler component of PAR measurements several significant improvements in tracking system performance are practically achievable including: lower state estimate uncertainty, increased measurement origin certainty, increased identifiability of target maneuvers and increased tracking system robustness.
