1) beam jitter
光束抖动
1.
The far-field intensity distribution for coherent combining and incoherent combining with conformal focusing transimitting is numerically calculated, and the effect of phase error, beam jitter, and fill factor is studied in detail to make a contrastive study of coherent and incoherent combining.
为了比较不同合成方案的远场效果,对聚焦发射的相干合成和非相干合成光束远场分布进行数值计算,从控制相位误差、光束抖动和阵列占空比等三方面对这两种方案的远场特性进行比较研究。
2) light beam vibration frequency spectrum
光束抖动频谱
3) delay variation constraints
时延抖动约束
1.
A Low Cost Multicast Routing Algorithm with Delay and Delay Variation Constraints;

2.
Delay constraints and delay variation constraints must be taken into account for interactive real-time application such as video conferences.
多播路由算法在组播应用中是至关重要的,对视频会议等交互式实时组播业务来说,不仅要考虑时延约束,而且要考虑时延抖动约束。
4) ultra-low jitter optical pulse
超低抖动光脉冲
5) whipping
[英]['wɪpɪŋ] [美]['wɪpɪŋ]
抖动,颤抖
6) antenna boresight pointing instability
天线波束指向抖动
1.
In this paper,the effect of antenna boresight pointing instability on SAR image quality is studied.
研究了天线波束指向抖动对图像质量的影响,分别给出了等效斜视情形下天线波束方位向多频抖动和距离向多频抖动对成像质量影响的理论分析和仿真结果。
补充资料:光束
分子式:
CAS号:
性质:光线通过一定面积时的集合。分为同心光束和平行光束。前者由发光点所发射光线而构成;它与球面波相应。后者为发光点在无限远处发出的光束,它与平面波相应。
