Abstract
The application describes a security inspection apparatus and a method of controlling the same. An example security inspection apparatus includes a body fixed in the field and an electromagnetic imaging device installed on the body. The electromagnetic imaging device includes a two-dimensional multi-input multi-output array panel, including at least one two-dimensional multi-input multi-output sub-array and a control circuit. Each two-dimensional multi-input multi-output sub-array includes transmitting antennas and receiving antennas, with the transmitting antennas and the transmitting antennas being arranged such that equivalent phase centers are arranged in a two-dimensional array. The electromagnetic imaging device further includes a signal processing device configured to reconstruct an image of an inspected object based on an echo signal received and a display device configured to display the reconstructed image of the inspected object.
