中文摘要:
      随着船载双通道雷达天线频率的不断提高,天线角度标校所需要的远场距离条件越来越无法满足。通过对双通道雷达天线自跟踪系统的深入分析,给出了交叉耦合产生的机理,并以此为基础阐述了近场效应对校相和角度标校的影响。给出了当前解决近场效应的4类常用的应对方法,经实际工程验证和对比分析,在近场距离条件下,近场阵列天线法是解决雷达天线角度标校最适宜的方法。最后,以X频段天线为例进行了实际测试,结果证明该方法操作简便、数据稳定可用,并已在多次卫星测控任务中得到了验证。
英文摘要:
      As the work frequency of the shipboard double channel radar increase, the condition of far field angle calibration is more and more difficult to satisfy. Through the auto track system analysis of the double channel radar, this paper states the reason of causing cross coupling. On the basis, this paper states the influence of near field effect to phase and angle calibration. This paper provides 4 methods to solve the near field effect, through realistic engineering testing and contrast, the method of using near array antenna can appropriately solve the angle calibration problem of radar antenna on near field effect condition. At last, the X band antenna has been practical tested, the method of using near array antenna has been proved easy to operate and the data is stable which has been verified in satellite monitoring and control tasks.
