Abstract

Disclosed are various embodiments for improving the accuracy of a phase associated with the radar signal by identifying a spectral signature associated with a radio frequency (RF) impairment and performing digital predistortion to enhance the radar performance and to compensate for the impairment that causes offset or imbalance of the phase rotator output cause signal distortion or otherwise degrade of the phase of the signal. The self-calibrating mechanism of the present disclosure is configured to identify the impairments, determine a spectral signature associated with the impairment, and optimize the phase error through digital predistortion of the RF signal based at least in part on the spectral signature associated with the impairment.
