Design and implementation of fast detection system for ocean evaporation duct

In order to study the occurrence regularity and detection method of ocean evaporation duct phenomena, and to evaluate the height and intensity parameters of the duct, a fast detection system for ocean evaporation duct is designed. The system consists of measuring buoy, receiving terminal and data processing software. Data acquisition of temperature, humidity and air pressure at different height is completed by the buoy based on ZigBee wireless networking technology. And they are transmitted to the receiving terminal by the communication radio inside the buoy body. After data quality control and calculation processing, the atmosphere modified refractive index profile is calculated by software, then the height and intensity parameters of evaporation duct can be obtained. The sea trial results show that the system can obtain the height and intensity parameters quickly in the case of evaporation duct appearance, and has the characteristics of high measurement efficiency, good practicability and stable operation.
