| 摘要: |
| 为使具有稀疏阵的三维成像声呐在成像信噪比、角分辨率及稳定性方面均具有良好的性能，提出包含主副瓣比、旁瓣高度和、主瓣宽度、通道间幅相误差4个因素的评价函数。改进优化过程，在保证阵增益、降低阵元失效影响的同时，使优化结果对幅相误差不敏感。通过对不同优化过程及实验结果进行分析，验证提出的目标函数可以使三维成像声呐具有更好的综合性能。 |

| Abstract: |
| Areasonable cost function comprising of max main-sidelobe ratio, sidelobe energy, mainlobe width and amplitude-phase errors is proposed to improve the performance of 3-D sonar with thinned planar array in imaging SNR, angular resolution and stability. Optimization of process, in which guarantee the array gain and reduce the effects of element failure at the same time, the optimization results are not sensitive to the amplitude and phase error. Analysis results of beam patterns with different cost functions and experimental results indicate that performance improvement is obtained by using proposed cost function. |
