WebBistatic Doppler shift is a specific example of the Doppler effect that is observed by a radar or sonar system with a separated transmitter and receiver. The Doppler shift is due to the component of motion of the object in the direction of the transmitter, plus the component of motion of the object in the direction of the receiver.

WebJan 1, 2008 · In general the bistatic Radar is a radar system in which the transmitter and the receiver are separated by a distance comparable to the target-to-receiver range used for target detection,... 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.
