Technical engineering whitepaper analyzing Differentiable Ray Tracing for Inverse Scattering and Building Permittivity Mapping within next-generation 6G cellular and radar architectures.
This paper formalizes Differentiable Ray Tracing for Inverse Scattering and Building Permittivity Mapping by establishing the multi-antenna RF channel matrix, noise covariances, and Cramer-Rao lower bounds for joint communication and radar estimation.
Extensive numerical simulations demonstrate that ISACTwins satisfies sub-millisecond detection thresholds while preserving full data throughput across wideband sub-THz carriers.
