衰落是由于发射机与接收机之间空间位置的微小变化引起的，描述小范围内接收信号场强中瞬时值的快速变化特性，是由多径传播和多普勒频移两者共同作用的结果，包括由多径效应引起的衰落和信道时变性引起的衰落，具有信号的多径时延扩展特性和信道的时变特性(Fading is caused due to a slight change of the position of the space between the transmitter and the receiver, the characteristics of the receiving signal field strength, the instantaneous value of the rapid changes in the description within, by multipath propagation and Doppler frequency shift of the joint action of botha result, time-varying fading caused by multipath effects and channel fading due to multipath delay spread characteristics and channel time-varying characteristics of the signal)

使用 matlab对CW、LFM信号模糊度进行计算并且绘制图像(Using MATLAB to calculate the ambiguity of CW and LFM signals and to draw images)

对每一路图像进行小波变换，分别到其水平、垂直、四十五度角方向的高频分量以及其低频分量，得到每路图像的小波金字塔； 按取较大值的原则对两幅图像的不同层次、不同特征层的信息图分别进行融合； 根据融合的各图像分量的小波序列，进行小波逆变换，得到最后的融合图像。 (Road images of each wavelet transform, respectively, to its horizontal, vertical, 45 degree angle the direction of high-frequency components as well as its low-frequency components obtained for each road image wavelet pyramid according to the principles of taking a larger value of the two images different levels of information mapping feature level fusion respectively the basis of integration of various components of the wavelet image sequences, inverse wavelet transform, to be the final fusion image.)

形态学分量分析 将图像分为纹理和平滑两部分 直接可以运行(Morphological component analysis for texture and smooth， the image is divided into two parts, can run directly)

the day of year是指这一年已经逝去的天数（包括当天） 。在平年中，它的取值范围为 1 到 365，在闰年中，它的取值范围 1到 366。编写一个 MATLAB 程序，输入年，月，日， 输入为对应的 the of year。 (the day of year is the year the number of days have been lost (including the day). In the average year, it ranges from 1 to 365, in a leap year, it ranges from 1 to 366. Write a MATLAB program, enter the year, month, day, enter the corresponding the of year.)
