主波束 meaning in Chinese
main beam
main lobe
Examples
- The result demonstrates that the variable phase center of fish antenna is much more steady than the lpda in the main beam
计算结果表明鱼骨天线在主波束相当宽的范围内,其可变相位中心的稳定度要优于对数周期偶极子天线。 - Noise and interference are inevitable in radar channel . they enter the received system through side or main beams , and reduce the system ’ s receiving signal - to - noise ratio ( snr )
在雷达信道中,不可避免地存在着噪声和干扰,它们通过天线方向图的边波束或主波束进入接收系统,从而降低系统的接收信噪比。 - Digital signal processing technologies were used to produce spatial and directional beam in adaptive antenna . then the main beam aims at the coming direction of desired signal and the side lobe points to the coming direction of interference signals
自适应天线利用数字信号处理技术，产生空间定向波束，使天线主波束对准期望信号到达方向，旁瓣或零陷对准干扰信号到达方向。 - Digital signal processing technologies were used to produce spatial and directional beam in smart antennas . then the main beam aims at the coming direction of reference user and the side lobe points to the coming direction of interference user
智能天线是利用数字信号处理技术，产生空间定向波束，使天线主波束对准期望用户信号到达方向，旁瓣或零陷对准干扰信号到达方向，达到充分高效利用移动用户信号并删除或抑制干扰信号的目的。 - The radiation patterns with and whitout radome are calculated , and the angle difference in the maximum field point of their main clot show the bse of the radome , the bse from - 15 degree to 15 degree in direction , that been calculated and compared with the excited experimented data shows they coincide quite well
有天线罩时的远区场和没有天线罩时的远区场相比较,两个主波束对应的角度差即是天线罩的瞄准误差,本文对方位扫描角从负15度到正15度进行分析。
