用Argo的netCDF文件计算海洋混合层和障碍层深度并通过M_Map工具包画出全球海洋MLD和BL的分布图。 P.S.: 1.需先安装m_map的toolbox。2.混合层及障碍层的定义参考Clément de Boyer Montegut, et al. "Mixed layer depth over the global ocean: An examination of profile data and a profile‐based climatology." Journal of Geophysical Research: Oceans 109(2004).(Use netCDF file to calculate the mixed layer and barrier layer and draw the global distribution figures with m map in matlab 1Please install m_map toolbox first 2The definitions of mixed layer and barrier layer used is provided by Montegut, et al 2004: Mixed layer depth over the global ocean: An examination of profile data and a profile based climatology.)

研究了重频参差相参脉冲串的频率估计算法。通过脉内相关积累，提高了新序列的信噪比。对新序列的相位差按参差重数抽样平均，减小了等效的相位噪声方差，利用重频参差比解相位模糊，扩大了频偏允许范围，降低了算法的信噪比门限。分析了本算法实现相参频率估计的条件，推导了相应信噪比门限的解析表达式，指出了信噪比门限与信号样本总数、参差重数、参差比之阎的关系。仿真结果表明：上述结论是正确的，在满足信噪比门限条件下，频率估计的精度接近相参脉冲串频率估计的克拉美一罗限(CRLB)。(Frequency Estimation for Staggered Coherent Pulse Train)
