Abstract: On condition that the vehicle is approximately uniform motion, a real-time speed measurement method used for Doppler navigation, which is not associated with angle parameter only based on measurement technology of frequency shift, is presented by applying a short-baseline linear array with three elements and compositely making use of velocity vector formula and Doppler shift as well as its changing rate equation. As compared with the available speed measurement method used for Doppler navigation, this method has potential superiority since it uses individual antenna beam. The analog calculation shows that the relative error less than 0 1 0 can be obtained when the radial distance is less than10km .
