本文阐述基于频域间接法的板块元基本原理，建立水下航行器三维网格模型，提出以任意路径运动的水下航行器回波特征预报方法。通过开展1∶20缩比的Benchmark潜艇回波特性水下声散射试验，验证了上述预报方法的准确性。研究表明，预报方法能够预测水下航行器以任意路径航行的回波特征，对水下运动目标的探测与识别有一定意义。
Planar element method based on indirect frequency domain method is described. By establishing 3D underwater vehicle meshing model, one method to forecast echo characteristics of underwater vehicle based on arbitrary path navigation is put forward. Through conducting Benchmark submarine scale model acoustic scattering experiment on lake, thus the validity of forecast method is verified. Research results show that the forecast method may predict the echo characteristics of underwater vehicle based on arbitrary path navigation, it has certain significance to the detection and recognition of underwater moving targets.
