摘　　要：针对在不同工程应用环境中离散频谱校正方法的选择问题,提出离散频谱最优校正方法的选择策略。该策略以校正方法的性能指标作为最优校正方法选择的主要依据,将校正方法选择问题转化为优化问题,通过计算优化函数获取选择结果。蒙特卡洛仿真实验的结果表明,在不同信噪比情况下,经选择策略产生的校正方法与其他4种单一校正方法(相位差法、比值法、能量重心法和全相位法)相比,校正精准度和实时性均有提高,因此证明了校正方法选择策略的有效性和可行性。With the selection problem of discrete spectrum correction methods in different engineering application environments,an optimal selection strategy is proposed, where the performance index of correction method as a criteria, the selection problem is turned into the optimization problem about the correction methods and the selection result is obtained by calculating the optimization function. The Monte Carlo simulation experiment results show that, under different signal-to-noise ratios, this correction method by the selection strategy has improved both the correction accuracy and real-time performance compared with the other four correction methods(phase difference method, ratio method, energy centrobaric method and all phase method), which proves the effectiveness and feasibility of this strategy.
