某火箭在空中沿直线做匀加速飞行，加速度为a ，发动机推力的波动必然会

引起加速度的波动，雷达以时间间隔T 不断测量该火箭距离原点的距离s ，而雷

达测量带有噪声。要求基于雷达对火箭距离的测量数据估计火箭的真实距离、速

度和加速度。

-A rocket in the air do acceleration in flight, along a straight line acceleration for a, engine thrust fluctuation will inevitably

Cause the fluctuation of the acceleration, the radar to time interval T measures the distance distance s origin, the rocket and ray

Measurement with noise. Requirements based on the radar of rocket distance measurement data to estimate the true distance and speed of the rocket

And acceleration.
