| 中文摘要: |
| 地面运动目标识别的难点是对不同类型车辆目标的识别。介绍了一种地面运动目标的信号识别方法——频谱相似性,详细地叙述了频谱相似性算法的原理,从理论上证明了算法的正确性。通过对实际采集轮式和履带车辆行驶时所发出的声信号作为样本进行训练,再对测试声信号采用频谱相似性算法进行识别,实验结果证明了该算法的可行性。与复杂声信号识别算法相比,该算法具有计算量小、易于移植到DSP等小型信号处理器件上的优点。 |

| The difficulty of ground moving object discrimination is to identify different types of vehicles.This article introduces a method of discriminating the ground moving object-Spectra Similarity.The principle of Spectra Similarity algorithm is described in detail and the validity of algorithm is proved in theory.The acoustic signals of wheeled vehicle and tracked vehicle are used as the samples for training,then the testing acoustic signals are distinguished with Spectra Similarity,and finally the feasibility of the algorithm is proved with experiment.Compared with the complex acoustic signal discrimination algorithm,this algorithm has advantages of less quantity of calculation and easily transplanting to the mini signal processor of DSP. |
