一、引言为了获得高空气象要素,可用气球或火箭携带无线电探空仪升空,由气象雷达追踪其运动轨迹,可算出不同高度层上的风向、风速。同时,探空仪将高空气象信息(温度、湿度、压力等)不断发回地面被气象雷达接收,根据这些遥测数据即可求出完整的高空气象要素供天气预报用。这显然要求对雷达探空数据进行实时的处理,因此近年来,国内各气象部门纷纷选用了8位字长的微型机系统来处理各类气象雷达探空数据。但由于高空气象雷达是自动跟踪与录取且采用小周期探空仪,数据率远较其它测风气象雷达为高,用8位机实时处理对速度与内存要求苛刻。因此,我们选用CMC-80双板机(除结构上多一块板外,其主要功能类似于其它Z80单板机)与主机(BCM-3)组成双
I. INTRODUCTION In order to obtain high-altitude meteorological elements, a balloon or a rocket carrying a radiosonde can be used to launch a spacecraft. The weather radar tracks its motion trajectory, and the wind direction and wind speed at different levels can be calculated. At the same time, the radiosonde sends the altitude weather information (temperature, humidity, pressure, etc.) back to the ground and is received by the weather radar. Based on these telemetry data, the complete altitude weather element can be obtained for weather forecasting. This obviously requires real-time processing of radar sounding data. Therefore, in recent years, various meteorological departments in China have chosen 8-bit microcomputer systems to deal with the sounding data of various types of weather radars. However, due to the high-altitude weather radar is automatically tracked and admitted and uses a small period sounder, the data rate is much higher than other wind-meteorological radars, with 8-bit real-time processing speed and memory demanding. Therefore, we use the CMC-80 double board machine (except for one more board in the structure, its main function is similar to other Z80 single board machines) and the host (BCM-3)
