The gain in a certain band of frequency is also calculated which shows good coincidence with the experimental results.
最后计算长八木天线在一定频带内的增益曲线。所得结果与实验结果吻合较好。
Under the room temperature and Nitrogen environment (eliminate the influence of water vapor absorption), we get the characteristic absorption spectrum of GaAs within the band of frequency.
在室温去除水份影响的氮气环境中，获得了低温生长的砷化镓在该波段的特征吸收谱。
Since K-Band frequency is 2.5 times higher than X-Band, the multipath signal generated by an intruder is also 2.5 times higher, vastly improving detection of slow and fast-moving targets.
因为K波段比x波段高2.5倍，由干扰产生的多信道信号频率也要高2.5倍，这极大改善了对慢速和快速移动目标的探测。
