Abstract

A device includes an input interface for receiving a target list for the MIMO radar sensor containing angular data including information regarding a target angle, at which the target is located, and channel data including information regarding reflection signals received from the target in individual channels in the MIMO radar sensor; a modeling unit for generating model data for each of the targets; a processor for determining a model error for each of the targets, containing information regarding a discrepancy between the channel data and the model data for the target; a selector for selecting one of the targets on the basis of the model error; and an adjustment unit for determining calibration coefficients for adjusting the channel outputs in the MIMO radar that compensate for the discrepancies between the channel data and the model data.
