高频率相控阵多普勒声雷达及其应用

A high frequency sodar with phased arra y and its application

回顾了过去十余年间高频率声雷达发展的背景。简要讨论了相控阵天线原理和高频率声雷达的优缺点。对其特殊用途作了扼要讨论。认为此种设备的性能、价格均较优,有着良好的发展前景,是充实我国中小尺度天气研究观测同的较为经济的遥感设备。

The background to the evolution of the high frequency sodar is reviewed. The principle of phased array is presented and so is the advantage of high frequency .sodar. Such kind of sodar is used for some special purposes. Being a remote sensing instrument, it is obviously with a promising future in an experimental mesoscale observing, network considering its lower cost as well as its satisfactory operations.
