摘要：
In this paper, the Cramer-Rao Bound (CRB) for scanning radar sensing is investigated, providing an algorithm independent bound on the angular estimation error. Based on the deterministic signal model, we first derive a numerical CRB for unknown real signal parameters. Then, the approximate closed-form expression of CRBs are further provided for the single target case. Meanwhile, the potential estimation error of various classical super-resolution sensing methods are quantitatively investigated in this paper, and compared with the presented CRB.
