底角
基角
基准角
Examples
- The bisectors of its base angles are equal .
底角的平分线是相等的。 - The base angles of an isosceles triangle are equal
等腰三角形的两底角相等。 - Firstly , the methods to restrain the effect of ship swing are studied for two - axes shipbome radar . two different methods based on ship rectangular frame and inertial frame are proposed separately according to consistence of radar base angle and beam angle
本文首先研究了舰载两轴雷达系统抑制船摇的方案，对雷达天线转角和波束转角一致和不一致的情况，分别提出了基于甲板坐标系稳定和基于大地坐标系稳定的不同方法。 - Considering the characters of 3 - axes coordinate system that is not included in ship rectangular frame or inertial frame , compensation conditions are deduced through studying the effects of ship - swing . the paper studies how to transfer line velocity and acceleration in the inertial frame to angular velocity and acceleration which correspond each axis , then gives the computer function scheme . servo control scheme which can overcome ship swing and realize moving - target accurate tracking is designed according to inconsistency of radar base angle and beam angle
针对三轴轴系既非甲板坐标系又非大地坐标系的特点，既研究了船摇对正交三轴雷达系统的影响，推导实现船摇不变性的补偿条件，又研究了将目标在大地坐标系中的线速度和线加速度滤波值折算到各轴对应的角速度和角加速度值的计算关系，并作出了计算机功能框图。
