We consider the problem of millimeter-wave (MMW) imaging for concealed objects using a transceiver antenna array. In practical implementations, larger array element spacing leads to aliasing in the spectrum of the received echo signals. In this paper, we propose a new imaging method by de-aliasing. Numerical simulation results show that in the case of aliasing, our proposed de-aliasing method outperforms the traditional method in both of resolution and clarity.
