High-Fidelity Near-Field mmWave MIMO Radar Simulation via Polarized Path Tracing

Accurate simulation of near-field millimeter-wave (mmWave) multiple-input multiple-output (MIMO) radars is essential for developing and validating high-resolution imaging systems, yet remains challenging due to large virtual apertures, multi-path propagation, and polarization effects that invalidate conventional far-fi...

Feature-Guided Diffusion for Non-Differentiable Inverse Rendering

This work proposes Feature-Informed Diffusion Evolution (FIDE), a fully black-box framework that requires no gradients or specific initialization: the renderer is treated as an opaque function whose only requirement is to produce images.
