The beacon will have a limited beamwidth and if the body-to-beam angle exceeds this a serious loss of signal will result . 这个信标器的波束宽度有限,如果弹体波束角超过了它,信号就会发生严重的衰减。
Broadband constant beamwidth sonar 宽带恒定束宽声呐
Ater level beamwidth 360 水平面波束宽度: 360
A robust wideband constant - beamwidth beamforming method for acoustic imaging 一种用于声学成像的稳健宽带恒定束宽波束形成方法
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。
