Original Abstract Submitted

A first input signal that corresponds to an output transmitted signal of a power amplifier of a vehicle radar system is received and the output power level of the transmitted signal is calibrated to optimize quality of the transmitted signal at the antenna reference plane (ARP). The proposed calibration method and apparatus allows to improve the output power calibration accuracy at ARP by compensating for reflected power at power amplifier output. The proposed apparatus uses the coupled and the isolated outputs of a bi-directional coupler to compensate the mismatch between the output of the power amplifier and the ARP; detectors at both coupler outputs measure both powers (coupled, isolated output) and apply respective correction on the calibration target to compensate for reflected power.
