| 摘 要： | 讨论了利用现有对窄带信号的分类来选择需要的宽带信号类型的方法.通过对宽带成像模型的分析以及比较宽带模糊函数与窄带模糊函数的联系,指出在一定条件下,按照窄带模糊函数分类的信号其宽带模糊函数具有相似的形状,该方法可用于宽带声成像时对信号的选择,仿真结果表明该方法是一种比较系统的信号设计和选择方案.

| Abstract: | The method that how to use narrow band signals' classification to choose wide-band imaging signal is discussed in this paper.By analysing wide-band imaging model and the relationship between wide-band and narrow-band ambiguity function,it's concluded that some wand-band signal can be choosing to image by using the classification of narrow-band signals in some definite condition.The simulation result shows that this method is a comprehensive signal design scheme. |
