| 中文摘要: |
| 以指向性函数一般表达式为基础,通过把倒圆台阵有基元损坏的情况转化为加权系数,得出其空间指向性函数和水平指向性;仿真分析了倒圆台阵基元损坏个数和位置对声纳空间指向性和水平指向性的影响,以及在一定环境下对声纳作用距离的影响,从而得出基元损坏达到何种程度时基阵的技战术性能不再符合要求的意见。 |
| 英文摘要: |
| Based on the directivity function,spatial directivity function and horizontal directivity of inverse conefrustum array are obtained via transferring its damage extent into weighted coefficients.Simulation analysis is performed to study the influence of amount of damaged elements on sonar directivity and the impact on sonar operation range under certain circumstance.Thus,conclusions of damage extent of elements unsuited for the demand of technical and tactical performances are drawn. |
