两个不同的蒙特卡罗仿真表明，通过采用这一新算法引人径向速度测量，不仅可以大大提高状态估计的精度，而且其估计性能和计算效率优于传统的EKF。

Two different Monte Carlo simulations show that the new algorithm cannot only improve state estimation accuracy but also is superior to EKF in estimation performance and computation efficiency.

最后，科学家测量了由于行星的引力拖拉而产生的恒星摆动，这就是径向速度。

Finally, scientists measure the star's wobble due to the planet's gravitational tug, known as the radial velocity.
