船载天线动态校相技术研究与实现

Research and Realization of Dynamic Phase Calibration Technique for Shipborne Antennas

针对船载单脉冲跟踪天线动态条件下不能校相,使用存在局限性的问题,进行了动态校相技术研究。通过分析产生相位差的原因,归纳出了影响相位值的各种因素,结合天线校相的原理,提出了在海上进行动态校相的3种实现方法并论述其原理与实现方案。通过在海上实际试验和测试,得到了测试结果,对3种动态校相的效果进行了对比,并说明三种动态校相方法具有很好的效果。

The dynamic phase calibration technique is studied because the shipborne monopulse tracking antennas can＇t calibrate the phase under dynamic conditions and are restricted for application. By analyzing the cause of the phase difference,various factors influencing the phase values are summarized,then considering the principle of antenna calibration,three methods for dynamic phase calibration on the sea are proposed and the principles and the implementation schemes for the methods are specified. Finally,the measuring results are gained through the actual trial and test on the sea,then the comparison among the methods is developed,and the conclusion is drawn that the three methods have good effects.
