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．Battlefield vocal targets were simulated by four kinds of vehicle voice, to get the tested data of vehicle noise and make an autocorrelation 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 autocorrelation spectrum analysis.
