We address the problem of three-dimensional (3-D) imaging for multiple-input multiple-output (MIMO) radar in the presence of phase synchronization mismatch between each transmitter-receiver pair. Although usually set to the default values (zero) in the popular practice , such inevitable errors often occur owing to imperfect knowledge of the local oscillators and could seriously deteriorate the imaging result. Hence in this paper, taking the sparse priori of target into account and motivated by t
