While Doppler radar is based upon scientific principles, it still suffers from very real problems that can lead to the arrest of innocent persons. The theory of operation of Doppler radar are explained, and the causes for errors in measurement are explained. Suggested improvements are listed that would help to eliminate many of the present inaccuracies in Doppler radar.
