Calibration to Mitigate Near-Field Antennas Effects for a MIMO Radar Imaging System

Blog Article

A calibration method for a high-resolution hybrid MIMO turntable radar Timer Module imaging system is presented.A line of small metal spheres is employed as a test pattern in the calibration process to measure the position shift caused by undesired antenna effects.The unwanted effects in the antenna near-field responses are analysed, modelled and significantly mitigated based on the symmetry and differences in Project Patterns the responses of the MIMO configuration.
