走航雷达测波仪由两个分系统组成:雷达测高系统和加速度系统。前者测量船艏到波面的距离变化;后者测量船艏处的升降。两者的代数和反映了波高。雷达测波仪的方块图如图一所示。图中加速度计安装在船艏处的稳定平台上,因此加速度计只是将垂直加速度变化转换为与其成正比的位移变化,加速度计内的机电转换器,将此位移变化转换成调制电
The cruise liner radar consists of two subsystems: a radar altimetry system and an acceleration system. The former measures the distance between the ship and the wave surface; the latter measures the lift at the bow. The algebraic and the two reflect the wave height. Radar wave meter block diagram shown in Figure one. The accelerometer is installed on a stable platform at the bow of the ship. Therefore, the accelerometer only converts the vertical acceleration change into a displacement change proportional to the accelerometer. The electromechanical converter in the accelerometer converts the displacement change into a modulated electricity
