secondly, a beam-hardening correction algorithm for single material object is given in the paper, which is more precise than polynomial approaching correction algorithm and more rapid than common iterative algorithm
其次，本文给出了单成分被测物体的射束硬化校正算法，该算法较多项式近似校正算法更加精确，并且显著快于一般的迭代算法。
first, according to the orthonormal quality and the rational choice of working point of the sonar array three shafts frame, the structure of the models is predigested preliminarily; secondly, according to the quality indexes and the coupling quality between frames, relatively small quantum is neglected . so the complex non-linear coupling models of the sonar array are predigested farther; lastly, considering the characteristic of the model coefficient matrix, the methods of the low rank polynomial approach and the error simulation are introduced . so the models are predigested again
首先从声纳基阵框架结构的正交性和工作点的合理选择出发，使模型的结构得以简化；其次根据系统性能指标及框架间耦合性强弱，忽略相对小量，对声纳基阵复杂的非线性耦合模型进一步简化；最后考虑模型系数矩阵的特点，运用低阶多项式逼近和误差仿真的方法，实现了对模型的再次降阶简化处理。
