说明：  m序列的小东西，用在SIMULINK里面(m sequence of small things, which in SIMULINK)

数组变换！逆序，将数组倒置！将一个二维数组行和列元素互换后到另一个二维数组中(Array transformation ! Reverse , the array upside down ! Will be a two-dimensional array of rows and columns after the swap element into another two-dimensional array)

给出两个chirp信号相加后，由瞬时频率定义求出的瞬时频率曲线，说明瞬时频率的不确切性；(The sum of two chirp signals are given, after the definition of instantaneous frequency derived from the instantaneous frequency curve, indicating lack of precision in the instantaneous frequency )

捷联惯性导航中地理坐标转换为直角坐标的matlab程序(Strapdown inertial navigation geographical coordinates are converted to rectangular coordinates matlab program)

捷联惯导系统放置在室内测试台上做静态测试，测试时间4500s。 1）取前180数据做粗对准（解析对准法）； 2）取第181s~900s数据做精对准（Kalman滤波法）； 3）从第901s开始做纯惯导解算； 4）用国军标的导航系统位置精度评价方法评估系统定位精度（分别计算CEP50 和 CEP95 下的定位精度）。(The strapdown inertial navigation system was placed on the indoor test bench for static test with a test time of 4500s. 1) take the first 180 data for rough alignment (analytical alignment method); 2) accurate alignment of 181s-900s data (Kalman filtering method); 3) pure inertial navigation solution is performed from 901s; 4) the positioning accuracy of the navigation system is evaluated by the method of position accuracy evaluation of the national military standard (the positioning accuracy under CEP50 and CEP95 are calculated respectively).)
