摘要
为了实现船载测控雷达海上无塔动态角度标校,通过分析副面馈电标校的原理,提出了一种在天线副反射面与馈源喇叭空间位置不对称的特殊情况下的角度标校新方法,即副面耦合器任意位置角度标校法,解决了对副面馈电角度标校法耦合孔精确定位难的问题。详细阐述了该方法的工作原理、标校步骤,最后通过试验验证了方法的正确性和有效性。
The method of Subreflector Feed Angle Calibration is the important approach of towerless angle calibration. For solving the problem that it is difficult to precisely locate the coupling-aperturo in the subreflector feed- back method of angle calibration, a new towerless angle calibration method is presented under the condition that the subreflector of antenna and the feedback horn are not symmetrical. The theory and steps of the method are in- troduced particularly. Finally, the correctness and the efficiency of the method are validated by experiments.
