A Novel Data Calibration Method for MIMO Near-Field Millimeterwave Imaging in Human Security
MIMO array is a very effective millimeter wave imaging system which can be used for human security inspection. Due to the inconsistency between the equivalent phase center and the actual transmit-receive antenna positions, we need to calibrate the original receiving data so that we can use FFT imaging method for fast reconstruction. In this paper, a data calibration method is proposed. According to the actual MIMO array, multiple calibration reference centers are selected to calibrate the near-field data, and then the FFT method is used for fast image reconstruction. Simulation results show the effectiveness of the method.
