| 英文摘要 | the signal noise ratio (snr) enhancement effects of spontaneous brillouin scattering spectrum on brilloluin optical time domain reflectometry (botdr) sensing system have been analyzed theoretically and demonstrated experimentally through changing the modulated pulse format. with the same pulse width or same spatial resolution, the snr is larger for triangular pulse. take the width of 200 ns as an illustration, the snrs of the coherent detection power spectrum for trapezoidal pulse and triangular pulse increase 3 db and 4.8 db relative to that of rectangular pulse respectively. the corresponding spectral linewidthes are narrowed and the sensing distances are also increased by about two times from the rectangular pulse to the triangular pulse. this phenomenon will be helpful to improve the spatial resolution or achieve longer sensing distance in the botdr sensing system at the same systemic conditions.
