Title: Pulse compression radar

Abstract: The invention is concerned with a bi-phase decoder in which compensation is provided for Doppler shift. In the phase decoder of the invention, the signs and magnitudes of the components of the received signals in the in-phase and quadrature axes are determined and errors caused by Doppler shift are detected by detecting changes in the product of the signs of the two components at times when the magnitude of a predetermined one of the components exceeds that of the other.
