摘　　要：以水下航行器的噪声源定位为研究背景,综合论述了基于空间傅里叶变换的近场声全息技术的研究现状,重点研究了算法误差、重建稳定性和滤波方法,分析了近场声全息技术目前仍需解决的问题,并结合Patch近场声全息、矢量水听器等新技术给出了相应的建议,旨在为近场声全息应用到水下噪声源定位提供依据。In regard to the localization of noise source for underwater vehicles, such as torpedoes and mines, the current studies on the near-field acoustic holography（NAH） based on spatial Fourier transform are discussed with emphasis on algorithms＇ reconstruction error, reconstruction stability and filtering methods. The problem in NAH technology, which still needs to be solved, is analyzed. Further, corresponding suggestions about applying such new technologies as Patch NAH and vector hydrophone to location of underwater noise source are offered.
