摘　　要：为了解决地面火箭人工增雨随机试验中不同移向的目标云催化后不能完全覆盖目标区的问题,提出以雷达回波移向轴线确定火箭人工增雨目标区和对比区的方法,该方法放宽了对作业目标云移动方向的要求。为得到更多的试验样本,在满足试验条件的情况下,对较长时间的降雨过程以150min为间隔取样,有利于增加随机试验的样本数,减小试验周期,便于进行作业效果的统计检验。In order to solve the problem that target cloud moving to different direction could not completely cover target area in the ground precipitation enhancement random tests,the method via the moving axis line of radar echo to determine the target area and contrast area was put forward. The method relaxed the requirement to the moving direction of target cloud. Under the meeting test conditions,the samples were collected at 150- minute interval for a long time rainfall process to get more experiment samples and shorten experiment circles. Thus,it will be easy to carry out the statistical test of operation effect.
