说明：  基于HSM（harmonic-to-subharmonic）的基音提取算法。本算法通过对HSM建模，消除了基音提取过程中基音减半或增倍的现象，大大提高了准确性能。(Based on HSM (harmonic-to-subharmonic) of the pitch extraction algorithm. HSM model by the algorithm, the extraction process to eliminate the pitch halving or pitch doubling phenomenon, greatly improving the accuracy of performance.)

说明：  杂波的统计模型仿真程序，有相关瑞利分布模型、相关对数正态模型、相关weibull模型、相关K分布模型。(Statistical model of clutter simulation program, related Rayleigh distribution model, correlation of log-normal model, correlation weibull model, the relevant K distribution model.)
