| 摘 要： | 采用双并行马赫曾德尔调制器产生高斯脉冲一阶微分和二阶微分型超宽带脉冲雷达信号和光载无线电传输技术,通过仿真研究了两种超宽带脉冲雷达信号在标准单模光纤中的传输特性.结果表明,高斯脉冲一阶微分型脉冲随着传输距离的增大而不断展宽,而高斯脉冲二阶微分型脉冲则先压缩后展宽.经100km标准单模光纤传输之后,在传输终端采用色散补偿光纤对传输信号进行不同程度的色散补偿,可获得满足美国联邦通信委员会规范要求的不同宽度高斯脉冲一阶微分和二阶微分型脉冲信号.

| Abstract: | Monocycle pulse and doublet pulse used for ultra wideband (UWB) pulse radar are generated with dual parallel Mach Zehnder modulator (DPMZM). Based on the fadio over fiber (RoF) technology, the transmission performance of the UWB pluses over standard single mode fiber (SSMF) are theoretically analyzed. It is found that monocycle pulse is broadened with the increase of transmission distance, while doublet pulse is firstly compressed and then broadened. Monocycle pulse and doublet pulse with different width satisfying the FCC requirements of UWB pulse radar can be obtained, when the accumulated dispersion of the radar signal is compensated in different degree with dispersion compensation fiber (DCF) after 100 km transmission over SSMF. |
