Improved probability hypothesis density filter-based time difference of arrival passive localization and tracking method for UAV swarms
This paper proposes a Peak-Width-Weighted Unscented Gaussian Mixture Probability Hypothesis Density (PWW-UGMPHD) algorithm to address the critical challenges of multi-target tracking divergence and cardinality estimation distortion in traditional PHD filtering. These issues typically arise from low Signal-to-Noise Rati...
