代码说明:

雷达进行PD测速主要是利用了目标回波中携带的多普勒信息,在频域实现目标和杂波的分离,它可以把位于特定距离上、具有特定多普勒频移的目标回波检测出来,而把其他的杂波和干扰滤除。因此要求雷达必须具备很强的抑制杂波的能力,能在较强的杂波背景中分辨出运动目标的回波。

  • vensim dss软件(Vensim DSS 6.4E)
    Vensim可提供一种简易而具有弹性的方式,以建立包括因果循环(casual loop)、存货(stock)与流程图等相关模型。 使用Vensim建立动态模型,我们只要用图形化的各式箭头记号连接各式变量记号,并将各变量之间的关系以适当方式写入模型,各变量之间的因果关系便随之记录完成。而各变量、参数间之数量关系以方程式功能写入模型。透过建立模型的过程,我们可以了解变量间的因果关系与回路,并可透过程序中的特殊功能了解各变量的输入与输出间的关系,便于使用者了解模型架构,也便于模型建立者修改模型的内容。

  • 改进的自适应阈值Canny边缘检测
    针对传统Canny 边缘检测算法的阈值需要人为设定的缺陷,本文提出了一种新的自适应改进方法。该方法根据梯度直方图信息,提出梯度差分直方图的概念,同时,对图像进行自适应分类处理,使得算法不仅不需要人工设定阈值参数,而且还能有效地避免Canny 算法在边缘寻找中的断边和虚假边缘现象。对边缘信息丰富程度不同的灰度图和彩色图像运用该方法寻找边缘的实验结果表明,对于在目标与背景交界处的多数像素梯度幅值较大的图片,该算法具有边缘检测能力强、自适应能力强的优点
