摘要
为了便于野外试验 ,对多普勒声雷达天线作了重新设计 .本文对新设计的集合式数字多普勒声雷达作了介绍 ,对比试验结果说明新设计的声雷达测量风速和风向的结果与系留气艇测量结果相符很好 ,其性能与过去国内和国外分离式天线多普勒声雷达的性能相当 .在西藏高原试验中 ,新设计的多普勒声雷达进行了 40多天连续探测 .声雷达探测结果发现在西藏高原当雄地区存在烟柱式上升运动 ,其垂直速度可达
A new antenna of Doppler acoustic rader was designed for convenience in field experiment. The new assembled digital Doppler rader was introduced in this paper. The results of comparison experiment show that the speed and direction of wind detected by the new rader conicide with those by tethersonde,and its functions are equivalent to those of Doppler acoustic radar with separated antenna developed previously in China and other countries. A continuous detection of the new designed rader was carried out for more than forty days in Tibetan plateau experiment. The results show that a plume upward motion exists in Dangxiong area of Tibet and its vertical velocity reaches about 1m/s. [
