本文介绍了雷达天线的扫描波束理论,采用了用波束宽度描述天线辐射方向图的方法。
With different scan beams, acceleration voltages and scan rates, we get different domain widths. The relationship between the inverted width and scan parameters was investigated.对于不同的扫描电压、扫描电流和扫描速率得到了不同的畴反转宽度,并且研究了畴反转宽度与扫描参量之间的关系。
The beam scan of a GJ-2 electron beam accelerator was improved with a 58 % increase in the scan width.对一台GJ - 2型电子加速器的扫描装置作了技术改造,产品上的扫描宽度增加58%。
