摘　　要：浅水多波束换能器主要声学指标能够直接或间接地反映系统性能指标,因此利用水池试验对系统换能器声学性能指标进行检测,不但能够初步掌握系统的性能,而且可以降低湖试或海试的风险。通过概括多波束测深系统核心性能与换能器声学指标的对应关系,按照水声计量检定规程和方法,论述了主要声学指标的计算方法,研究了自由场条件下声学指标的检测方法和注意事项,并结合国产多波束系统水池试验,验证了方法的可行性。The main acoustic performance of the shallow water multibeam echo sounder transducer can directly or simultaneously reflect the performance of the system.The acoustic index of the system transducer can be detected through the experiment in the pool,which can preliminarily have a grasp of the performance of the system and reduce risk of the experiment in lake or sea.This paper summaries the corresponding relationship between the core performance of multibeam bathymetric system and the acoustic index of transducer,discusses the calculation method of the main acoustic index,studies the detection method and precautions under the condition of free field acoustic index with the acoustic verification regulation and measurement,and verifies the feasibility of the method in combination with the pool test of the domestic multibeam echo sounder.
