Chapter 32: Open Problems and Future Directions

Learning Objectives

• Identify the sim-to-real gap as the central challenge for deploying learned RF imaging
• Formulate dynamic scene imaging with temporal priors and real-time constraints
• Propose primitive-based scene representations as compact alternatives to voxel grids and neural fields
• Evaluate foundation models as general-purpose priors for RF imaging
• Analyze scalability bottlenecks and hierarchical strategies for large-scene reconstruction
• Derive information-theoretic resolution limits and their connection to channel capacity
• Read and write RF imaging papers with rigorous methodology
