点波束 meaning in English

point beam
spot beam

Spot beam antenna
点波束天线
The spot - beam design in the satellite - based cellular communication systems is discussed mainly
摘要讨论了卫星蜂窝通信系统的点波束设计。
Currently there are two typical spot - beam models with equal beamwidth and equal spotarea
目前等波束宽度模型和等点波束面积模型是两种常用的点波束模型。
On the basis of discussing the analyzed restraint relationship between the link loss and the spot - beam antenna gain a new spot - beam model of optimum design named link level balance spot - beam model is proposed
在分析链路损耗与点波束天线增益之间制约关系的基础上，提出了一种新的点波束优化设计模型链路电平平衡点波束模型。
The calculation result shows that the model can keep the balance of the link level budget margin among the different spot - beam cellars , the onboard power in satellite can be used more effectively and the model is possessed of better applied value
计算结果表明，该点波束模型能使各点波束小区的链路电平预算余量达到平衡，并使星上功率得到更有效的利用，弥补了现有模型的不足，具有较高的应用价值。
