| 中文摘要: |
| 为了使得航天器的设计、制造与试验能够并行开展，同时降低试验成本、缩短试验周期，在最近十余年，国外发展了直接声场试验技术（DFAT）。这种新型的噪声试验技术与混响场试验相比更为方便、快捷，极大地提高了试验效率。针对未来飞行器研制与试验，论述了DFAT技术的进展情况。从扬声器阵列的布置方式、控制技术的改进和DFAT技术目前所具备的能力现状等三个方面阐述了DFAT试验系统的组成与发展，对近十年来国外开展的典型DFAT试验进行了梳理，并总结了在试验中发现的声场一致性、与混响场的差异、试验件结构响应和驻波等相关问题。对DFAT技术的后续应用前景进行了展望，提出了我国发展DFAT技术所面临的问题和挑战。 |

| To achieve design, manufacture and testing of the spacecraft in parallel, decrease the test cost and reduce the cycle, in recent decade, the direct field acoustic testing (DFAT) technique was developed in foreign countries. Compared with reverberant field acoustic test, this new acoustic test technology has the advantages of convenience and shortcut, which enhance the testing efficiency remarkably. In terms of spacecraft development and test in the future, the progress instance of DFAT was discussed. The DFAT system constitution and development were elaborated in speaker matrix configuration, improvement of controlling technique and current situation. Typical DFAT cases developed by foreign countries in recent 10 years were discussed and some problems like uniform of the acoustics field, contrast with reverberant acoustic field, structure response of the test article and standing waves were summarized. The future application of DFAT technique was expected. Some problems and challenges of developing DFAT technique in China were indicated. |
