RELATIVISTIC AND CLASSICAL DOPPLER ELECTRONIC TRACKING ACCURACIES

Abstract

The first order Doppler effect has in general been used in electronic tracking. With the emphasis upon accuracies of tenths of a foot per second and less, this approach is no longer permissible. This study has taken a fundamental look at the Doppler effect. Five steps were developed which enable the exact derivation of the Doppler equations for any system. Six different configurations of transmitter, receiver, and vehicle were investigated and the results applied to a number of present and future operational Doppler systems. It was determined that for velocity accuracies of a foot per second, or better, the second order relativistic or classical equations must be used. The receipt of a zero Doppler shift was also investigated and it does not necessarily imply zero line of sight velocity.
