摘　　要：为进一步提高舰用水声对抗器材回波诱骗的逼真度,对典型水面船的回波亮点特征进行分析。基于Kirchhoff近似公式和四路径方法构建水面船声散射模型,对比分析改变船舶尺寸、船舶类型和观测角度对水面船回波亮点特征的变化规律。研究结果表明,回波亮点个数与船舶类型密切相关,船舶尺寸、类型和观测角度均可改变亮点相对分布位置及亮点对应回波幅值,船舶尺寸和观测角度直接影响水面舰船回波展宽宽度。研究结果对水面舰船回波模拟工作提供一定指导意义。In order to further improve the fidelity of echo decoy of the underwater acoustic countermeasure equipment for surface ships,a study on the echo highlights characteristics of typical surface ships is carried out.The surface ship acous-tic scattering model is established based on the Kirchhoff approximation theorem and the four-path method in this paper.The effects of ship size,ship type,and observation angle on the echo highlight characteristics of typical surface ships are ana-lyzed.The results show that the number of echo highlights is closely related to ship type.The relative distribution position and amplitude of the echo highlights are changed with ship size,ship type,and observation angle.The width of echo broad-ening is directly affected by ship size and observation angle.These research results can provide guiding significance for sur-face ship echo simulation.
