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.
