【摘要】 采用边缘探测技术测量布里渊频移量的误差会对海表温度测量精度带来很大影响。文章根据布里渊频移量与海表温度之间的关系以及边缘探测技术的测量原理,建立了边缘探测技术中布里渊频移量的测量误差与海表温度精度的理论模型,分析了边缘探测技术对海表温度测量精度的影响。仿真结果表明,在布里渊频移量为7.2~7.9GHz的范围内,布里渊频移量的最大测量误差约为0.33MHz,根据布里渊频移量反演的海表温度测量精度为0.0105℃。该研究对海表温度的监测系统设计有着很好的指导意义。更多还原

【Abstract】 The error of measuring Brillouin frequency shift based on brim detecting technology has great influence on the measurement precision of sea surface temperature. According to the measurement principle of brim detecting technology and the relation between Brillouin shift and sea surface temperature, a theoretical model which monitors sea surface temperature by detecting Brillouin scattering frequency shift based on brim detecting technology is established. The effect of brim detecting technology on the Sea surface temperature measurement accuracy is analyzed. The results show that the maximal error of measuring Brillouin frequency shift is approximately 0.33 MHz while Brillouin frequency shift is distributed from 7.2~7.9 GHz, and the measurement precision of sea surface temperature is 0.010 5 ℃. This study has good instruction significance to the design of sea surface temperature monitoring system.更多还原
