本文研究二维雷达跟踪飞行器及估计问题。首先在实际的物理模型下构造离散时间的状态空间方程;接着应用卡尔曼滤波器来跟踪估计飞行器的位置和速度,目的在于能够适合于非平稳的矢量信号和噪声情况;最后用仿真算例验证本文方法的有效性和可行性。
This paper studies two-dimensional radar tracking aircraft and estimation problems. Firstly, the state space equation of discrete time is constructed under the actual physical model. Then the Kalman filter is used to track the position and speed of the aircraft. The purpose is to fit the non-stationary vector signal and noise condition. Finally, The effectiveness and feasibility of this method.
