arXiv:2606.28396v1 Announce Type: cross Abstract: Millimeter-wave (mmWave) radar perception is limited by data scarcity: models trained on existing radar datasets fail to generalize to new objects, environments, and sensing trajectories. We present RadarTwin, a framework for generating deployment-specific radar training data before real data collection. Given a 3D reconstruction of a target space (phone LiDAR, robot-mounted sensing, or RGB-to-3D), RadarTwin uses a vision-language model to infer radar-relevant surface materials and a physics-based ray tracer to synthesize raw frequency-modulate
The proliferation of AI models, particularly in embodied AI and robotics, is creating a critical need for high-quality, diverse training data that traditional collection methods struggle to provide efficiently.
This development addresses a fundamental bottleneck in the advancement of AI perception systems, allowing for more robust and generalizable models in real-world applications.
The ability to generate synthetic, deployment-specific radar data significantly reduces the cost and time associated with training mmWave radar systems, enabling wider adoption and faster iteration cycles.
