matlab版读取串口gps信息的图像化程序(A GUI program of matlab reads gps info from GPS by rs232 port。)

说明：  针对高动态 环 境 下 突 发 信 号 检 测 问 题，提 出 基 于 高 阶 项 逐 级 消 去 的 非 线 性 调 频 （ｎｏｎ－ｌｉｎｅａｒ　ｆｒｅｑｕｅｎｃｙ ｍｏｄｕｌａｔｉｏｎ，ＮＬＦＭ）信号参数估计算法，利用合理近似，将其转化为相对简单的线性调频 （ｌｉｎｅａｒ　ｆｒｅｑｕｅｎｃｙ　ｍｏｄｕ－ ｌａｔｉｏｎ，ＬＦＭ）信号参数估计问题，并提出两级调频率逼近法用于ＬＦＭ 信号参数估计，具有原理简明、计算复杂度低 等特点，便于实际工程应用．(To detect burst signals in high dynamic environment, a non-linear frequency modulation (NLFM) based on high-order item elimination is proposed. Modulation (NLFM) signal parameter estimation algorithm, using reasonable approximation, is transformed into a relatively simple linear frequency modulation- The problem of LFM signal parameter estimation is discussed. A two-stage frequency modulation approximation method is proposed for LFM signal parameter estimation. It has simple principle and low computational complexity.)

说明：  主要用于电子罗盘实验，对于新手调试入手很快(Mainly used in electronic compass experimen,For beginners, debugging starts quickl)

c++写的车辆监控的程序，框架搭好了，核心代码也实现了。串口接收GPS数据，实时在图上显示(c++ to write the vehicle monitoring process, the framework and setting up the core code is implemented. Serial port to receive GPS data, real-time display in the map)

用于卡尔曼滤波，静态GPS信号接收时，对GPS信号进行分析(Kalman filtering is used, a static GPS signal reception when the GPS signal is analyzed)
