Method for measuring physical characteristic to air bubble wake of a ship using a portable sensor

摘要

PURPOSE: A method for measuring a physical characteristic of air bubble wake of an ocean ship using a portable sensor is provided to obtain the same measuring effect to a multi sensor of two dimension without the two-dimensional multi-sensor. CONSTITUTION: A method for measuring a physical characteristic of air bubble wake of an ocean ship using a portable sensor is as follows. A measuring ship with a sensor for measuring the physical characteristic of the bubble wake of a ocean ship is prepared(S401). Bubble wake is generated by the moving of an ocean ship for measuring the physical characteristic of the bubble wake of the ocean ship(S402). The physical characteristic of the bubble wake is measured using the sensor and the measured signal information and the location information of the ocean ship and the measuring ship at the time of measurement are stored together(S403). The measured location difference depending on the measured time of the physical characteristic signal of the bubble wake measured is corrected(S404).
