Abstract: Based on the Kalman filter, the paper discusses the influence factors on robust and estimate accuracy when rebuilt the ballistic, and demonstrates the range rate data functions in rebuilding the ballistic strictly. The analysis and simulation demonstrates that using the velocity and position data simultaneously is one of the basic ways to improved the sysem's stability and data processing quality
