Abstract

Abstract : This study gives explicit closed‐form expressions of the stochastic Cramer–Rao bounds (STO‐CRBs) on direction‐of‐departure and direction‐of‐arrival estimation accuracies for collocated multiple‐input–multiple‐output (MIMO) radar with unknown spatially coloured noise. In some special cases, i.e. the CRB of direction estimation accuracy for monostatic MIMO radar, the white noise scenario is discussed. Theoretical comparisons between the STO‐CRBs and the deterministic ones are presented. Finally, these bounds are numerically compared.
