| 中文摘要: |
| 通过研究目标声纳窄带离散回波模型,论文建立了水下体积目标宽带离散回波模型。并结合均匀线性阵列信号模型,推导出了基于散射亮点形状、距离、方位角等反映目标尺度信息参量的体积目标宽带离散线性均匀阵列回波模型,为水下体积目标探测与尺度估计提供了可靠的理论依据。仿真与实验对比结果证明了模型的正确、有效性,说明了其实用价值。 |

| This paper sets up broadband echo model of volume target under water based on studying the narrowband dispersed echo model in sonar target.Referring to the signal model of the uniform linear array,we have inferred the broadband echo model of volume target in uniform linear array based on the target size information parameters which were reflected through the form,distance,and azimuth etc of scattering highlight.It will offer the theoretical foundation reliably for detecting and size estimating of small yardstick target under water,the results of comparison between simulation and experimental prove the correctness and efficiency of the model,and show its practical value. |
