单指向水听器以及双圈十元阵的实验研究

Unidirectional Hydrophone and an Experimental Research on the Ten-element Double Circle Array

从单指向水听器的定义出发,分析其在水下波束形成中的应用,并利用单指向水听器构建了双圈十元阵这一特殊的基阵模型,以此阵为基础在消声水池进行了实验研究,验证了单指向水听器应用于水下波束形成时的有效性和实用性。从理论、仿真和实测数据处理等各方面都证实单指向性水听器及其应用于基阵波束设计的可行性和优异性能。

From the definition of unidirectional hydrophone, its application is analyzed in underwater beamforming, and by using the unidirectional hydrophone constructs the ten - element double circle array . Based on this array, an experiment is finished in anechoic water pool ,which is investigated to verify the unidirectional hydrophone used in underwater beamformer of validity and practicability. In this dissertation it is proved by theory, computer simulations and real - data processing that unidirectional hydrophone is feasible solution for beam optimization and improves the performance of the beam pattern with strong robustness.
