讨论密集间距阵分步波束形成时频混合处理模型和拖曳试验结果、试验结果证明理论模型正确，可以工程实现．当子阵接收的背景噪声中流噪声是占优势的分量时，对试验子阵系统和相同条件下传统的半波长间距阵相比，系统性能指数提高了１７ｄＢ左右。
This paper discusses the time-frequency hybrid processing model and the towing test results of dense pitch array step beamforming. The experimental results show that the theoretical model is correct and can be realized by engineering. When flow noise is the dominant component of the background noise received by the sub-array, the system performance index is improved by about 17 dB over the experimental sub-array system over the conventional half-wavelength spacing matrix under the same conditions.
