N2 - We compute Cramér-Rao bounds (CRBs) for the target and compound-Gaussian clutter parameters using radar array measurements. In particular, we compute CRBs for (i) complex target amplitudes, (ii) spatial covariance matrix of the speckle component, and (iii) texture distribution parameters. We first derive general CRB expressions under an arbitrary texture model and simplify them for gamma and inverse gamma texture distributions. We use the generalized Gauss-Laguerre quadrature to compute the CRBs for gamma texture whereas the CRBs for inverse-gamma texture do not require numerical integration. We use numerical simulations to validate our results.
