【摘要】 在水声对抗中,密排阵在超大功率发射情况下,基阵阵元之间存在较强的互辐射效应,导致阵元阻抗发生变化,使得聚焦波束发生劣化。根据已知压电换能器的大小,计算了八阵元的互辐射阻抗。将互辐射阻抗值考虑到辐射声场计算中,得到了在互辐射阻抗影响下的波束指向性图,分析了在互辐射效应下波束指向性劣化的程度。更多还原

【Abstract】 The compact array in the hypermegasoma power emission of the underwater acoustic countermeasure has intensive mutual radiation effect,lead to impedance on array bechance change and focusing beam became deteriorate, according to the size of piezoelectric transducer calculating the impedance of eight matrix element,directional response pattern can be depainted with the mutual radiation impedance calculating in the radiate sound field,to analyze the level of deteriorate under the mutual radiation impedance.更多还原
