介绍了一种在单一万向支架轴线的天线罩测试系统中,用极切角的方法测试出瞄准线误差曲线来推算出各个复合偏航和方位、俯仰角之间的三维瞄准线误差曲线的方法,并进行了实例验证此方法是有效的。用这方法测得的三维天线罩瞄准线误差曲线来分析天线罩对导弹控制回路的影响及导弹的稳定性和脱靶量是非常必要的。
A radome test system with a single gimbal axis is introduced. The error curve of the line of sight is measured by polar angle method to calculate the three-dimensional line-of-sight error curves between each composite yaw and azimuth and elevation This method is validated by an example. It is necessary to analyze the effect of the radome on the missile control loop and the stability and miss distance of the three-dimensional radome measured by this method.
