Webcurrent velocity is obtained from the Doppler shift of the received echo from the transmitter frequency. When the transmitter is located many kilometers from the receiver, the configuration is termed ‘bistatic’. For bistatic configurations, contours of constant time delay are ellipses with foci at the transmitter and receiver locations.
