摘　　要：设计并实现了一种基于大气折射指数剖面的气温、相对湿度和气压测量系统,包括数据采集板和手持接收终端两部分,可同时测量多点数据。介绍了各元器件的型号、部分电路原理图以及软件流程。系统测量结果与自动气象站输出数据项比较。结果证明,该系统达到了精度指标(温度:±0.1℃;相对湿度:±3%;气压:±0.2 hPa),其使用方便、精度高、功耗低、可靠性好。可搭载于舰船之上,测量数据可用于预测蒸发波导。The system that measures air temperature, pressure, relative humidity in low altitude atmosphere based on atmosphere refractivity is presented. The system includes a data collection board and portable receiving terminals to realize multipoint data acquisition. The model of component, schematics and software process are introduced. The measuring results are compared with those from automatic weather station, which show that the system meets the precision requirement （temperature： ±0. 2 ℃, humidity： 3% , air pressure：±0. 2 hPa）. Being convenient, battery-efficient, reliable and with a high precision, the system can be carried on the ship to forecast evaporation duct
