舰载雷达搜索天线有很窄的主波束,当船随着波浪起伏而摇摆时,主波束也随之而摇摆,因而,扫着目标的概率就会降低。如果天线装在稳定平台上,不管船如何摇摆,平台总是保持水平,这样问题就能解决,而且也能提高探测到的目标高度和方位数据的精度。然而如今设计的稳定平台的机械装置常常重于天线好几倍,由于这种天线都装于桅杆的最高处,天线和稳定平台的重
The carrier radar search antenna has a narrow main beam, and as the ship swings with the undulations, the main beam swings along with it, thus reducing the probability of sweeping the target. If the antenna is mounted on a stable platform, the platform will always be level, no matter how rocked the ship, so the problem can be solved and the accuracy of the detected target height and bearing data will be improved. However, today the stability of the platform design of the mechanical device is often several times heavier than the antenna, as this antenna are mounted on the mast of the highest antenna and the stability of the platform weight
