摘　　要：在雷达、导航、测控、GPS应用等领域,要提高电子系统的测量定位精度,必须要精确获得大气引起的电波时延参数。针对目前电波时延计算方法的缺点,提出了一种实时测量大气时延的新方法,并与其它方法进行了实际比较。实验表明:该方法具有高精度、机动、全天侯、实时性等特点和实用价值。In domains of radar,navigation, observation and control,GPS application and so on,we must precisely obtain the radio-wave delay parameter which the atmosphere causes if we want to improve the t and orientation accuracy of the electronic system. In view of the shortcomings of the present radio-wave delay computational method, the paper proposed a new method for real-time measurement of atmosphere delay, and made a actual comparisons of this method with the other means. The experiment indicated that this method has both high accuracy, mobile, whole day, real-time features and practical value.
