一种多波束接收阵的分析与设计

Analysis and Design of a Multi-beam Receiving Array

提出了一种用于接收的多波束半球阵的设计方法。基阵由均匀布放在半球圆周上的5个半波阵子压电换能器组成,阵元间采用"接力"式的工作方式,形成5个并行波束,实现波束对半空间的全向覆盖,并可实现对目标方位的粗略估计。制作出换能器及基阵硬件,通过水池实验验证了该方法的有效性。

A design approach of multi-beam hemisphere array using for receipt is presented. The array is made up of five half-wavelength piezoelectric transducers equably planted on the circumference of a hemisphere, and the ＂relay＂ working mode is adopted between elements. The array can provide five parallel beams covering the half-space, and the target orientation can be estimated roughly. The transducers and array hardware are manufactured and the validity of this approach is verified by experiments.
