directional sensitivity meaning in English

方向灵敏度

Directional sensitivity for the hot - wire measurements at very low wind velocity
极低风速下热线测量的方向特性
Angular calibration of radar antenna system is composed of the calibration of angular error sensitivities ( also called directional sensitivity ) , adjustment of cross - coupling of azimuth and elevation signals , and the calibrations of system errors such as antenna axial system error , dynamic delay and so on
雷达系统天线的角度标校包括对系统角误差灵敏度(又称定向灵敏度)的标定、方位俯仰信号交叉耦合的调整以及对天线轴系误差、动态滞后等系统误差的标定。
This paper mainly studies the coupling error caused by induction voltage phase difference , and fluctuation of directional sensitivity caused by changes in near - field difference slope . the trend of system sum and difference phase difference , directional sensitivity and cross - coupling with change in distance is compared and discussed when the antenna is in the near - field and at a certain elevation
本文着重研究了因近场感应电压相位差引起的耦合误差，以及近场天线差斜率变化引起的定向灵敏度的变化；讨论了天线在近场并有一定仰角的条件下，随着距离的变化，系统和、差相位差、定向灵敏度与交叉耦合的变化趋势。
