3 PRINCIPLE OF OPERATION The Doppler speed log measures ship's speed by using the Doppler Effect, which is observed as a frequency shift resulting from relative motion between a transmitter and receiver or reflector of acoustic or electro- magnetic energy. A common example of the Doppler Effect is a...
Page 12 - REMARKS ON USAGE; Remarks on Usage
4 REMARKS ON USAGE Remarks on Usage The DS-80 measures ship’s speed by detecting the Doppler shift frequency of the echo reflected by a watermass (water layer containing plankton and other micro- organisms) located within the measuring area, which is usually about 2 m. In some instances, however, no...
