一、引言宽角电扫雷达用电子控制天线波束扫描,无需天线机械转动,可同时跟踪多批目标,反应速度快,数据率高等优点己众所周知。但由于其设备复杂和成本昂贵,在很多战术场合的应用受到限制,由于有限电扫技术的发展出现了电扫天线和天线座机械转动相结合的相控跟踪体制,使得设备复杂程度和成本明显降低,从而使其在一定的战术场合得以推广应用。本文给出一种有限电扫雷达的最新设计。在10°×10°角覆盖内具有良好的方向
I. INTRODUCTION Wide-angle electric sweep radar uses electronically controlled antenna beam scanning, which does not require mechanical rotation of the antenna. It can simultaneously track multiple targets and has the advantages of fast response and high data rate. However, due to its complicated equipment and high cost, its application in many tactical applications is limited. Due to the development of limited electric-wave scanning technology, a phased-tracking system combining the electric rotating antenna and the mechanical rotation of the antenna base appears, which makes the equipment complexity and cost obviously Lower, so that it can be applied in certain tactical occasions. In this paper, we present a new design of a limited electric sweep radar. Good orientation in 10 ° × 10 ° angle coverage
