Abstract
Ultra-wideband (UWB) technology has become a research hotspot for high-precision positioning due to its high temporal resolution and robustness against multi-path interference. However, traditional angle estimation algorithms are limited in accuracy. To address this issue, this study proposes a high-precision angle estimation algorithm for UWB signals based on an iterative adaptive approach (IAA). By establishing a mathematical model of the received signal from an array antenna, a theoretical framework is derived, and an iterative optimization mechanism is designed to achieve precise parameter convergence. Experiments using the YunSDR Y750 demonstrate that the IAA algorithm significantly outperforms the multiple signal classification (MUSIC) algorithm, achieving an angle estimation error of less than 4.5 in 90% of cases (compared to less than 5.5 for the MUSIC algorithm). This algorithm effectively improves the accuracy and robustness of UWB signal angle estimation.
