摘　　要：为实现远距离探测,阵列孔径往往十分庞大,严重影响系统机动性和隐蔽性。奥米亚棕蝇双耳间距非常小,但却可以对其寄主实现高精度定位,研究表明此特性主要归功于其双耳之间的一种特殊耦合结构。将此耦合结构运用于阵列测向系统,可以在保证测向精度和空间分辨力的前提下,大大缩小阵列孔径。通过仿真分析了此仿生技术在小尺度阵列测向系统中使用的可行性,分析结果表明此技术在阵列测向系统小型化方面具有较大的潜力。For remote detection,the array aperture is ofen very large,the mobility and concealment are seriously influnced.The distance between the ears of Ormia ochracea is very small,but it can position the cricket precisely which is mainly due to the feature coupling structure,showed by some studies.When this coupling structure is applied in array-based direction finding system,the array aperture can be greatly reduced in the term of direction-finding accuracy and spatial resolution.The feasibility of the bionic technology applied in the direction finding system based on small-scale array is analyzed by simulation.The results of analysis indicate that this technology has greater potential in the miniaturization of array-based direction finding system.
