Optimal beamforming minimizes periodic PCRB for angle sensing in multi-user ISAC with unknown reflection coefficient under rate constraints, requiring at most one sensing beam.
A convex optimization formulation for robust MIMO radar beamforming under bounded PDF uncertainty, obtained via quadratic Taylor approximation of the PCRB and the S-procedure to convert infinite constraints into an LMI.
