Abstract :
The extremely high resolution of Ultra-Wideband (UWB) signal in time domain and range measurement precision makes it advantageous in precise positioning. The algorithm based on averaging TOA is effective in reducing error in the precision positioning of stationary targets. But for moving targets, severe error will be introduced which makes the method unusable. This paper presents two means to improve the performance of the original algorithm in dealing with moving targets, using radial velocity compensation and triangulation velocity compensation. The precision has been improved by 40% via triangulation velocity compensation method in the bistatic 2-dimension (2D) simulation.
