摘　　要：为兼顾传感器阵列的小型化与高性能,提出对小孔径阵列的接收信号进行仿生耦合处理,以扩展阵列的有效孔径。将寄生蝇耦合听觉结构看成一个两输入-两输出系统,基于其振动方程,推导输出响应的具体表达式,构建信号处理模型,优化耦合参数,对阵列信号进行仿生耦合处理。仿真结果表明,仿生耦合处理放大了阵元信号间的相位差,虚拟地扩展了阵列孔径,能够在保证高性能的前提下实现阵列的小型化。In order to achieve miniaturization and high performance of the sensor array at the same time,the biomimetic coupled processing on the received signals by small aperture array is proposed to extend the effective aperture of the array. Considering the coupled auditory structure of parasitoid fly as a two-input two-output system,on the basis of its vibration equations,the expressions of the output responses are deduced, and the signal processing model is constructed,while the parameters are optimized. The array signals are processed by biomimetic coupling. Experimental results show that the biomimetic coupled processing can amplify the differences between signals of antenna elements, and extend the aperture of array validly,which can achieve array miniaturization on the premise of ensuring high performance.
