摘要：

民用航空的安全保障和民用机场的安全管理是国家高度重视的工作，为保障航空安全的需求，对民用机场鸟击的防范工作也提出更高的要求。面对此问题，中国测试技术研究院声学研究所针对不同类型的声波驱鸟产品、远距离定向声波驱鸟系统等进行声学性能的测试及分析研究。该文重点介绍一种基于参量阵技术驱鸟设备的声学测试，测试基于与委托方达成共识的自编测试作业指导书，采用全消声室自由场环境和实际工况现场环境两套方案，最后针对其声压级、辐射指向性、工况声衰减特性等指标给出评价效果，证明该基于参量阵技术驱鸟设备的声学性能能够满足委托方的基本使用需求。

Abstract: The safety of civil aviation and the safety management of civil airports are highly valued by the state. In order to ensure the safety of aviation, the requirements for the prevention of bird strikes at civilian airports are also raised.In response to this problem, the NIMTT conducted acoustic testing and analysis of different types of sonic bird repeller products and long-range directional sonic bird repeller systems.This paper focuses on an acoustic test based on parametric array technology bird-repelling equipment.The test is based on the self-compiled test operation instructions agreed with the client, using the full anechoic chamber free field environment and the actual working conditions on-site environment.Finally, the evaluation results of sound pressure level, radiation directivity and sound attenuation characteristics of working conditions are given. It is proved that the acoustic performance of the parametric-based technology bird-repelling equipment can meet the basic needs of the client.
Keywords: directional acoustic wave;parametric array;acoustic measurement;sound radiation directivity;sound attenuation under working condition
