摘要
针对现代炮兵战场上的目标识别问题,阐述了火炮射击声信号数据—发射波、弹道波和爆炸波的特征,介绍了火炮射击声信号AR模型谱估计的方法和步骤,利用MATLAB信号处理工具箱具体实现了三种不同类型火炮发射波的AR模型谱估计,并对一批样本成功进行了分类识别实验,探讨了火炮射击声信号AR模型特征在现代战场火炮目标识别中的意义和应用价值。
In order to solve the question of target recognition on modem artillery battlefield, this article expounds the characteristics of cannon firing sound signal data-shooting sound wave, ballistic trajectory sound wave, and exploding sound wave, It introduces the method and process of AR model spectrum estimation of cannon shooting sound signal. With the MATLAB Signal Processing Toolbox, it makes out the AR model spectrum estimation of three different cannon shooting sound waves. And it classifies some samples of shooting sound wave successfully. At last, it discusses the meaning and application value of AR model characteristics of cannon shooting sound signal in modem battlefield cannon target recognition.
