摘要
本文以４种车辆噪声来模拟战场声目标，以实测的车辆噪声进行自相关谱分析，在提取特征量的基础上绘制了直方图．探索了利用噪声自相关谱，对声目标进行模糊模式识别的可行性．
Battlefield vocal targets were simulated by four kinds of vehicle voice, to get the tested data of vehicle noise and make an autocorrelation spectrum analysis. On the basis of abstracting their characteristic parameters, we drew their statistical histogram and explored the feasibility of making vocal targets fuzzy model identification through noise autocorrelation spectrum analysis.
