摘要: |
一种特殊的均匀圆形阵列(SUCA)安装在水下监测系统中的浮体系统上。针对SUCA的特殊性,建立了SUCA的模型,运用模式空间理论推导出其方向图公式,并在此基础上对其半功率波束宽度和无模糊条件进行了研究和分析。通过与均匀圆形阵列(UCA)进行比较,得出结论:SUCA 半功率波束宽度略大于UCA,并且其无模糊条件比UCA范围更广。研究表明SUCA的性能与UCA相似,具有工程实用价值。 |

Abstract: |
A special uniform circular array (SUCA) was fixed on the underwater monitoring system’s floater system; SUCA’s model was created based on SUCA’s particularity. Then half-power beamwidth and unambiguous condition of SUCA were reseabased by theory of mode-space. Results show that half-power beamwidth and unambiguous condition’s scope of SUCA is wider than UCA, and SUCA is practicable in engineering application. |
Keywords: special uniform circular array patterns half-power beamwidth unambiguous condition |
