根据手机号码判断城市，需要手机号码7字段对应城市的信息。(According to cell phone number to determine the city, needed a mobile phone number 7 corresponds to the city' s information field.)

本文从理论上对LFM-CW 雷达进行了信号分析，并对LFM-CW 雷达的信号 处理方法进行了简单研究，最后通过仿真程序验证了该信号处理方法（距离/多普勒处理） 在计算运动目标距离和速度时的正确性，为LFM-CW 雷达信号处理提供了理论依据。(This paper analyze the signal of LFM-CW radar by theory, and research the signal process method of LFM-CW radar. In the end, this paper validate the signal process method’s correctness to calculate the moving target’s distance and speed by emulate program. This paper offer the theory for the signal process method of LFM-CW radar.)

产生随机信号观测样本，不同信噪比和归一化频率。利用基于FFT的自相关函数快速计算方法估计其自相关函数。(Generate random signal observation samples, different signal to noise ratio and normalized frequency.Based on FFT calculation method of the autocorrelation function to quickly estimate the autocorrelation function.)

一个雷达回波模拟的matlab程序包,含有在RCS服从卡方分布,瑞利分布,对数正态分布下目标的的雷达散射截面模拟子程序， 具有径向加速度,径向速度,径向距离的雷达回波模拟,有3-D图形显示.(A radar echo matlab simulation package, containing the RCS subject to chi-square distribution, Rayleigh distribution, lognormal distribution of the target radar cross section simulation subprogram, with the radial acceleration, radial velocity, radial distance the radar echo simulation, there are 3-D graphical display.)

使用matlab来处理各种格式的数字图像(use matlab to process image)

这个子程序主要写的是由判决变量量化判决出QAM复振幅，(This subroutine is written by the decision variable to quantify the judgment QAM complex amplitude,)

说明：  用有限元差分发求解一维热传导，并作做出二维图线和三维温度变化图像(One dimensional heat conduction is solved by finite element difference distribution and plotted)

说明：  编程计算图形的面积。程序可以计算圆形，长方形，正方形的面积，运行时先提示用户选择图形的类型，然后，对圆形要求用户输入半径值，对长方形要求用户输入长和宽的值，对正方形要求用户输入边长得值，计算出面积的值后将其显示出来。(Calculate the area of graphics programming. Program can calculate the round, rectangular, square area, run-time prompts the user to first select the type of graph, and then the radius of the circle requires the user to input the value of the rectangle requires the user to input the length and width values, requires the user to input side of the square grow the value to calculate the value of the area after the show.)

一份关于lmfsoved 的matlab 代码，很好用的！(A report on lmfsoved the matlab code, a very good use!)
