代码说明:

  有两个程序一个是关于frft的源程序,一个是应用frft对线性调频信号进行检测的程序,原理是以变换阶数(不同的分数阶域)为变量对观测信号进行分数阶变换,形成信号能量在时频平面上的二维分布,在此平面上按阈值进行峰值点的二维搜索即可检测线性调频信号并估计其参数。(There are two procedures one on frft the source, one application frft linear FM signal detection process, the principle is to transform the order of (different fractional domain) as the independent variables on the observed fractional signal change, the formation of signal energy in two-dimensional time-frequency plane distribution in this plane, the peak threshold value by two-dimensional linear FM signal can be detected search and estimate its parameters.)

  • near-field-inverse-problems
    本书详细介绍了基于近场测试数据的逆散射问题的相关知识及其具体应用,这是近场问题的一个很好的例子,在人们都关注高频远场问题的背景下,提出近场的问题,对于计算电磁学的发展很有启发意义,我们的工程实际中,除了高频远场的应用外,低频近场也占有很大的份额,基于进场的反演是一个新兴的课题,需要我们共同去研究!(Book introduced in detail based on near field test data of the inverse scattering problem related knowledge and its practical application, this is a very good example of near field problems, people are concerned about the background of far field problem of a high frequency in the, near field is proposed, for the development of electromagnetism calculation is instructive. In the actual engineering, in addition to the high-frequency far field of application, low frequency near-field also occupies a large share of, based on the inversion approach is a new and developing subject, we go to study!)
