An experimental correction model for UWB through-the-wall distance measurements

This paper presents error analysis and error correction for UWB signal based ranging using P410 RCMs (PulsON 410 Ranging and Communication Modules). We propose a theoretical model for precise ranging in complex indoor environments. The model intends to correct the range error incurred by rich multipath propagation and signal penetration through walls. The experimental results show that through the model based error correction, the distance measurement accuracy can be improved significantly.
