干扰信号估计仿真程序程序，matlab仿真程序(Interference signal estimation procedure simulation program, matlab simulation program)

惯性导航系统属于一种推算导航方式．即从一已知点的位置根据连续测得的运载体航向角和速度推算出其下一点的位置．因而可连续测出运动体的当前位置。惯性导航系统中的陀螺仪用来形成一个导航坐标系使加速度计的测量轴稳定在该坐标系中并给出航向和姿态角(Inertial navigation system is a dead reckoning navigation mode. That is from a given point according to the measured continuous carrier heading angle and velocity calculates the next location. The current position which can)

采用极大似然估计辨识方法，对系统参数进行辨识。(The maximum likelihood estimation method is used to identify the system parameters.)
