PRINCIPLE OF OPERATION The Doppler speed log measures ship's The relative motion causes the Doppler shift speed by using the Doppler Effect, which is and the ultrasonic waves reflected at the observed as a frequency shift resulting from watermass (plankton or any underwater relative motion between a transmitter and objects) are received at the frequency of fr = receiver or reflector of acoustic or electro- fo + fd where fd is the number of frequency magnetic energy. A common example of the shift
