拉曼光纤放大器（ ramanfiberamplifier ,简称rfa ）利用高强度的泵浦光与信号光在光纤中的非线性相互作用实现信号光的直接放大，但是由于光纤的拉曼增益系数谱很不平坦，所以同一泵浦光源对不同波长信号光的增益就存在很大的差别,因此,用单泵浦光源来放大波分复用( wavelengthdivisionmulti - plexing ,简称wdm )信号光时，各信号光的增益值就有很大差异， wdm信号增益的平坦度对光信噪比( opticalsignal - noiseratio ,简称osnr )有重要影响。 - The characteristics of the method is that it can modify the guidance coefficients automatically according to the errors between the actual trajectory and the standard trajectory , this is the essential of the standard trajectory guidance . it don " t need any pre - knowledge of the coefficients , this simplifies the problem greatly . following that , the method of predicting the falling site of the instant retuning trajectory is studied
这一方法的特点是从反馈增益系数对再入段纵程偏差修正的本质出发，利用实际弹道和标准弹道的偏差，通过调节升阻比增量，不断修正再入段纵程偏差，最终确定反馈增益系数；这一方法的优点是在求解反馈增益系数时，不必依赖先验知识选取初值，使反馈增益系数的确定更为简便。
