WebFeb 27, 2024 · Speed through water or speed over ground. This is one of the most common doubt seafarers have about Doppler log. The Doppler log measures the speed with respect to the surface reflecting the transmitted wave. In deep water the transmitted wave gets reflected by water layer which gets denser as the depth increases.
WebThis corresponds to the echoes movements across the PPI on a true motion display. The own ships course and speed are your ships true motion during the period of observation. 49. Radiation Hazards and Precaution MULTIPLE ECHOES Multiple echoes can be created by reflection between own ship and an object before the scanner finally collects its energy. Web(PSD) method is also used to eliminate nois data. Third, the ship motion criteria for the case of the passenger ship is determined and it compare to the existing criteria. 1. Introduction Ship motion at sea can disturb the balance of crew members and passengers making Motion Induced Interruptions (MII).
