摘要
近几年来,随着计算机图形学,计算机网络和通讯技术的迅速发展,我国的一些气象业务部门正在应用UHF或VHF信道传输各种气象数据、天气图和雷达回波图等。本文介绍用UHF波段手持式报话机把多普勒雷达速度回波图传输到江苏省气象局的原理。
With the rapid development of computer graphics and of computer networkand communication techniques in recent years, UHF or VHF channels have come intooperation in meteorological services for the transmission of meteorological data, weathercharts and radar echo images. In this paper the principles of a portable UHF bandtransceiver for transmitting the velocity echo images of Doppler weather radar to theJiangsu Provincial Weather Bureau are described in detail.
