- W2024303663 abstract "Source bearing estimation is a common application of linear sensor arrays. The Cramer–Rao bound (CRB) sets a lower bound on the achievable mean square error (MSE) of any unbiased bearing estimate. In the white noise case, the CRB is minimized by placing half of the sensors at each end of the array [MacDonald and Schultheiss, JASA (1969)]. However, many realistic ocean environments have a mixture of both white noise and correlated noise. In many shallow water environments, the correlated ambient noise can be modeled as cylindrically (two-dimensionally) isotropic. This research designs a fixed aperture linear array to maximize the fisher information for bearing estimation under these noise conditions. The optimum array is designed to maximize the minimum fisher information over an a priori bearing range. The elements of the optimal array are located closer to the array ends than uniform spacing, but are not so extreme as in the white noise case. The optimal array results from a trade off between minimizing the measured noise and maximizing the array bearing sensitivity. Depending on the source bearing, the resulting improvement in MSE performance over a uniform array is equivalent to a 3 to 5 dB improvement in input SNR. [Work supported by ONR.]" @default.
