Enhancing Radio Frequency Radar Data Interpretability through Explainable AI Techniques

The rapid advancements in radar technology have led to radar innovations in various applications, including advanced driver assistance, autonomous vehicles, activity recognition, vital sign monitoring and environmental monitoring. Novel machine learning techniques are often used to train radar solutions based on large radar datasets containing annotated time series from pulse radars, mmwave radars of UWB radars. However, the black-box nature of traditional machine learning algorithms often hinders the interpretability of radar-based decision-making systems. This PhD research aims to bridge the gap between radar applications and human understanding by investigating Explainable Artificial Intelligence (XAI) techniques tailored for radar data.

Expected Outcomes:

This research will contribute to the field of Radio Frequency (RF) radar applications and artificial intelligence by providing tools and methodologies to enhance the interpretability of radar-based systems.

This includes

• Developing Radar-Specific XAI Models: Design novel XAI models and techniques customized for radar data, considering the unique characteristics, such as high-dimensional data, temporal dependencies, and noise patterns.
• Interpretable Feature Extraction: Investigate methods for extracting interpretable features from radar data that capture relevant information while reducing complexity.
• Real-time Explainability: Explore real-time or near-real-time XAI solutions for radar applications to support decision-making in dynamic environments.
