首先,概要分析了非周期排布天线的形式,分析了美国地基雷达原型机(GBR-P)天线波束性能;然后,结合一个工程实例,介绍了旋转超级子阵在车载机动式雷达天线中的设计方法,并进行仿真分析计算;最后,给出了实测结果,与仿真结果相互吻合,具有一定的工程指导意义。

The aperiodic array arrangement and the radiation performance of the ground based radar-prototype antenna are discussed firstly. Then with an engineering example, the design method of tilted super sub-arrays is introduced, which are used to compose array antennas of vehicle mounted radars. Both simulation and experiment are carried out, the results of which are also presented and agree well with each other, validating the design method and analysis. This work has certain instructional significance to relevant engineering practice.
