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!)

Overview The Simulink model shows an example how the Kalman Filter can be implemented in Simulink. The model itself is configured with a Gaussian process connected with a Kalman Filter. To directly use this model, one only needs to provide model prarameters including parameters of the Gaussian process, which are state space matrices, A, B, C, and D, initial state, x0, and covariance matrices, Q and R and similar parameters for the Kalman Filter, which can be in different values to mimic the model mismatch, plus the state covariance, P. The following examples show how this model can be used. The Kalman Filter can also be used as a standard model block to be connected with any other systems

说明：  本文提出了一种基于混沌加密的DCT域二值图像数字水印算法.该算法首先利用混沌序列将含有版权信息的有意义二值图像水印进行加密,然后利用人眼视觉系统(HVS)的特性将原始载体图像进行块分类,最后将不同强度的水印分量嵌入到不同类的图像块DCT中频系数中去.利用混沌序列对水印进行加密,使水印本身具有安全性,对数字作品进行双重保障.通过高斯噪声,椒盐噪声以及JPEG压缩和剪切等攻击试验,表明了该算法具有较好的鲁棒性.(Encryption in DCT domain is proposed. Firstly, the meaningful binary image watermark containing copyright information is encrypted by using chaotic sequence, and then the original image is classified by using the characteristics of human visual system (HVS), Finally, the watermark components with different intensities are embedded into the DCT intermediate frequency coefficients of different types of image blocks. Chaotic sequences are used to encrypt the watermark, so that the watermark itself has security and double protection for digital works. Experiments on Gaussian noise, salt and pepper noise, JPEG compression and clipping show that the algorithm has good robustness)
