Random Array Generation Method for Identifying Noise Source of Moving Vehicles

提出一种用于汽车运动噪声源识别的二维随机阵列三步生成技术,它包括阵元法布局、基线筛选和模拟评价。利用这种技术可以大幅度提高随机目标阵列的生成速度,由此得到的随机目标比十字阵列有更好的特性。通过实车试验,更进一步验证了这种方法生成的随机目标阵列的有效性。

A three-step generation method of two-dimensional random arrays for identifying the noise source of a moving vehicle is presented, including the layout of array elements, base-line filtering and simulation evaluation. Using this method can greatly speed up the generation of random target array and obtain a characteristic better than that of a cross array. Real vehicle tests further verify the effectiveness of the method of random target array gen- eration.
