中文说明：这是Kalman滤波的一个简单应用实例，实现了在某一物体在重力场做自由落体运动，观测装置对其位移进行检测，在传感器受到未知的独立分布随机信号的干扰下，对该物体的运动位移和速度的估计。这是一个二维系统，代码简单，每行代码都有注释，方便大家理解。希望下载后给个好评哦！
English Description：
This is a simple application based on Kalman filtering, implemented in an object in a gravitational free fall, observation devices to detect its displacement, unknown independent distribution in the sensor under the interference of random signals, motion estimation of displacement and velocity of the object. This is a two-dimensional system, the code is simple, every line of code has comments, so as to facilitate understanding. Praise if I want to download it!
