短波波段 meaning in Chinese

short wave band
short-wave band
skip band

In order to hold the performance of the antenna array of hf radar the length of antenna array is also very long
高频超视距雷达工作在短波波段,为了保持一定的天线阵性能,天线阵尺寸通常也较大。
Because of the presence of the first - order sea echoes with dominant amplitude , the doppler resolution technique which based on the range - velocity transformation is needed to extract the targets information in hf radar
高频雷达工作在拥挤的短波波段,由于绝对占优的一阶海浪回波的存在,必须采用基于距离?速度谱变换的多普勒频率分辨技术来处理杂波,以提取目标信息。
Short wave is used for wireless communication which the wavelength is from 10m - 100m . in fact , the high frequency part of medium wave usually belongs to short - wave band . so many short wave communication equipments ’ band was extended to 1 . 5 - 20mhz
实际上,许多人也把中波的高频段( 1 . 5 - 3mhz )归到短波波段去,所以现有的许多短波通信设备,其波段往往扩展到1 . 5 - 20mhz 。
