原文:
Kalman Filter example Let us begin with a simple example: a one-dimensional radar that measures range and velocity by transmitting a pulse toward an aircraft and receiving the reflected echo. The time delay between pulse transmission and echo reception provides information about the aircraft range (r), and the frequency shift of the reflected echo provides information about the aircraft velocity (v) (Doppler effect).

卡尔曼滤波器示例让我们从一个简单的示例开始：一维雷达，通过向飞机发射脉冲并接收反射回波来测量距离和速度。脉冲传输和回波接收之间的时间延迟提供有关飞行距离的信息\ (r) ，反射回波的频移提供有关飞行速度\ (v)的信息（多普勒效应）。
