-我退出了。 描述测量方法和程序的标准化，以确定测向仪（DF）的特性，从而以统一的方式分析测向性能。给出了标准试验条件，讨论了试验设备。讨论了测向仪灵敏度和系统精度测量，并考虑了时间要求和干扰。

- Inactive-Withdrawn. Describes the standardisation of measurement methods and procedures to enable the determination of a direction finder's (DF) characteristics which will permit analysis of DF performance in a uniform manner. Standard test conditions are given and test equipment is discussed. Direction finder sensitivity and system accuracy measurements are discussed, and time requirements and interference are considered.
