相控阵雷达扫描波位和扫描时间的设计与优化

详细讨论了在相控阵雷达设计中扫描波位如何确定的问题。扫描波位的确定原则是使雷达系统既满足一定的检测概率和作用距离，又能在最短的时间内扫描整个空域。这就必须在波位驻留时间和平均增益损失等因素之间进行折衷。为了进一步节省扫描时间，还对如何利用数字波束形成（ Ｄ Ｂ Ｆ） 技术实现优化进行了探讨。

DESIGN AND OPTIMIZING FOR PHASED ARRAY RADAR'S SCANNING BEAM POSITION AND SCANNING TIME

This paper discusses how to set the beam position when designing the working process of phased array radar in detail. The criterion of setting is that the radar system can not only meet certain detecting probability and range but also scan the whole airspace during the shortest time. It must be compromised among beam position standing time, mean gain loss and so on. Furthermore,this paper discusses how to optimize the beam position by using the technology of Digital Beam Forming(DBF) in order to save time for scanning.
