Equivalent Fisher Information for Wideband DOA Estimation With Unknown Sensor Phase Errors

This letter derives the closed-form equivalent Fisher information matrix (EFIM) for single-source wideband DOA estimation with a uniform linear array in the presence of unknown sensor phase errors. Based on a deterministic frequency-domain model, the source coefficients are first concentrated out, and the phase-error n...
