beam scanning

基本解释

A novel frequency fixed beam scanning microstrip leaky wave phased antenna has been developed.
提出了一种崭新的带移相器双端口馈电微带漏波天线。
Its antenna beam scanning entirely electronically controlled beam scanning speed is not only high, but the number of beams, movement pattern can be arbitrarily controlled.
其天线波束的扫描完全用电子的方式控制，不但波束的扫描速度极高，而且波束的数目、运动方式都可以随意的控制。
Experimental studies on the domain inversion in LiNbO 3 crystal by electron beam scanning were performed.
对紫外激光诱导近化学计量比钽酸锂晶体铁电畴反转进行了实验研究。

With this, the scanning beam is not directed at any single spot, but moves around, so the plastic does not burn.
ECONOMIST: Recycling
To do that requires scanning the object beam through the target about a hundred different ways.
ECONOMIST: Microscopy
It works by scanning a laser beam across an object and manipulating the reflected light to produce an extremely narrow focal plane.
ECONOMIST: The Archimedes palimpsest: Eureka!

波束扫描
It is difficult for missile-borne stripmap SAR to gain the required wide-spread image in the terminal guidance because of narrow beam coverage and short imaging time. To solve the problem,a new scheme of beam scanning is proposed.
针对弹载条带合成孔径雷达(SAR)在末制导阶段由于波束覆盖范围窄和成像时间短,不易获得所要求的大面积图像的问题,提出了一种新的波束扫描方案,并根据导弹在末制导阶段的飞行特点,结合子孔径处理方法,对波束扫描参数进行了理论分析和设计。
