动态范围是比幅测向设备一项重要指标,在分析了比幅测向设备测向误差来源和机理基础上,针对目前常用的比幅测向动态范围定义和测试方法在检验样本设计上不尽合理之处,提出了符合简单随机抽样条件的比幅测向动态范围定义和测试方法,对比幅测向设备动态范围设计、分析、测试具有一定指导作用。

Dynamic range is one of the important performance requirements of amplitude-comparison DF(direction-finding)equipments.in this paper,on basis of analyzing the source and mechanism of signal direction measurement errors of amplitude-comparison DF equipments,the improperness of existing definition and measurement method of dynamic range of amplitude-comparison DF equipments,a new definition and measurement method of dynamic range of amplitude-comparison DF equipments is proposed which conforms to simple random sampling rule.It will provide to some degree guidance for design,analysis and measurement of dynamic range of amplitude-comparison DF equipments.
