Improving the Robustness of CNN-Based Human Detection in Multiple Raw UWB Radar Datasets

Abstract

Ultra-wideband (UWB) radar technology has gained significant attention for human detection, vital sign monitoring, and activity recognition applications. In this study, a robust deep-learning model capable of detecting human presence in different environments is developed. The model uses only the raw data obtained directly from the radar without preprocessing. The model is trained and tested on different datasets collected via the UWB radar. Transfer learning has been applied to fine-tune the model on datasets to improve the performance and generalization of the model. This study demonstrates the effectiveness of transfer learning in adapting UWB radar-based human detection models to different environments.
