英语翻译
OPTICAL generation of microwave and millimeter-wave signals is of great interest for many applications such as broad-band wireless access and sensor networks,software-de-fined radio,radar,and satellite communication systems.The key advantage of generating microwave or millimeter-wave signals by optical means is that very high-frequency signals with very low phase noise can be generated by beating two optical sig-nals with a wavelength spacing corresponding to the desired mi-crowave or millimeter-wave frequency.In addition,the signals can be distributed over an optical fiber by taking the advantages of the extremely low transmission loss of standard single mode

Answer 1

通过光学途径产生微波和毫米波信号对于很多应用都颇具吸引力,如 宽带无线接入和传感器网络,软件无线电,雷达,还有卫星通讯系统.通过光学途径产生微波或毫米波信号的主要好处是,可通过撞击波长间隔与所需微波或毫米波频率相对应的两个光学信号来获得相位噪声很低的高频信号.此外,所获信号可利用标准单一模式传输损耗极低的优势分布式地穿过光纤.
