一种L波段单脉冲天线的研制

Development of an L-band Monopulse Antenna Array

介绍了一种L波段单脉冲天线的研制。根据天线指标要求,提出了天线的总体设计方案,进行了天线的方向图综合,设计了天线的辐射单元。分别采用泰勒综合法和数值方法对天线的方向图进行了综合,实现了方位面的低副瓣设计和俯仰面的波束赋形设计。对研制的天线进行了实测,各项指标均满足要求。

In this paper, the development of an L-band monopulse antenna array was discussed in detail. The design projecr for this antenna is put forward and the array pattern synthesis is carried through. Taylor synthesis method and numerical method are adopted to synthesize the radiation patterns, and as a result, low side-lobe in azimuthal plane and shaped beam in vertical plane are realized, respectively. The designed antenna is rested with vector network analyzer and far-field measurement system. The results satisfy the design requirements well.
