查询词典 VHF

From the reason of speckling, this paper analyses the degree of speckles in UHF/VHF band SAR images.

本文通过研究相干斑产生的机理，分析了UHF／VHF波段SAR图像受相干斑干扰的程度。

VHF can also be reflected from clouds of increased ionisation in the E layer of the ionosphere.

VHF 可能并且被反射从增加的电离云彩在电离层的E 层数。

This layer normally refracts shortwave and mediumwave signals but is transparent to VHF radiation.

这层数折射短波和mediumwave 信号但通常是透明对VHF 辐射。

Center frequency of the system is 280MHz with a bandwidth of 10MHz. The sample frequency is 2GS/s. The system shows the lightning VHF source in 2-D, and the error for azimuth is less than 1 and 3 for elevation.

系统能够给出闪电VHF辐射源的仰角和方位角二维发展图像，对方位角的测量精度大于仰角，从标定结果来看，系统对方位角的测量误差在1度以下，而对仰角的测量精度随着仰角的减小而降低，对所分析的高仰角闪电，仰角误差一般不超过3度。
