波束方向 meaning in Chinese
beam direction
Examples
- The system is designed so that stray reflections of the user ' s signal against vehicles or buildings do not trigger abrupt changes in the direction of the beam
这个系统经过特别的设计，所以用户的讯号虽然会受到车辆或建筑的胡乱反射，但是并不会导致波束方向发生突兀的改变。 - The beam width is stretched . the algorithm performance has the very big weaken . but the convention beamforming algorithm performance is stabler , time delay unbalance , time domain sampling , plane wave supposition and array element the influence which creates to it is not big
通过比较,高分辨率算法在考虑上述情况后,波束方向出现偏差,束宽被展宽,幅度有很大的衰减,性能明显下降;而常规波束形成算法的性能较稳定,延时失配、时域抽样、平面波假设和基阵的幅相不一致对其造成的影响不大。 - With compensation of signal ’ s time delay from different radiating element by phase shifters , phased - array antenna can control array beam easily . because there are no mechanical devices for rotating beam , the phased - array antenna system can scan everywhere in beam covered areas in millisecand by stepping the phase shifters . it improves the tracking velocity of antenna towards the object , and becomes the development trends of weapon system antennas
相控阵天线利用移相器补偿信号到达辐射单元时间的差异,从而控制波束方向;天线没有机械旋转问题,只需改变移相器的设定值,波束便可以在毫秒级内扫描其覆盖空域内的任何地方,提高了天线对目标的跟踪速度,是目前武器系统天线的发展方向。
