摘要：

An Estimation of Signal Parameters via Rotational Invariance Techniques (ESPRIT)-based method is presented to estimate the gain-phase errors of both transmit and receive arrays in bistatic multiple-input-multiple-output (MIMO) radar. Unlike the recent ESPRIT-like methods, the directions of unknown targets and uncalibrated array steering vectors are first estimated with ESPRIT-based algorithm, and the array gain-phase errors are calculated subsequently. Compared to the existing ESPRIT-like methods, the proposed method is much more computationally efficient and has better performance. Simulation results confirm the effectiveness of the proposed method.
