　　Digital Radio-Theodolite System for Upper Air Soundings

　　采用单脉冲测角体制，通过跟踪气球携带升空的数字式无线电探空仪，测量探测作业阵地上空30公里高度内各层次上的大气温度、湿度、气压，计算出各高度层次上的风向、风速，为天气预报、气候分析和气象保障提供及时、准确的高空气象情报资料。该系统分车载式和固定式两种，可广泛应用于机场、试验基地及军用、民用气象台、站。

　　The mono-pulse angle measurement mode is adopted in this HT-QJ1 digital radio-theodolite system. Through tracking the radiosonde carried and raised up in the air by the ballon,the system can measure the temperature, humidity,atmospheric pressure at different layers of atmosphere up to 30km altitude,and calculate the wind direction & wind speed values at different atmospheric layers. Therefore,the system can provide precise meteorological information of upper air for weather forecasting,meteorological analyses and supports. The system has two versions:the mobile version and the fixed mounted version. The system can be widely used at airports,flight test ranges,military can civil meteorological stations.
