A Closed-Form Solution With Asymptotic Performance for Gain-Phase Error Self-Calibration Exploiting Toeplitz Structure

This article addresses the self-calibration of gain-phase errors in a uniform linear array. Existing closed-form calibration methods are primarily developed for signal models with external noise and cannot be directly applied to the traditional direction-of-arrival estimation problem with internal noise. To address thi...

Adaptive Space-Frequency Basis Selection Methods for Signal Frequency Band Sensing and Fast Wideband DOA Estimation With Passive Sonar Data Verification

In the wideband direction of arrival (DOA) estimation problem, signal measurement equipment typically receives wideband signals with different frequency bands in practice. Thus, the commonly adopted assumption in most relevant methods that the incident signals share the entire frequency band under monitoring is inappro...
