Abstract :
Given the complexity of a radar system with Digital Beamforming a number of error influences can appear due to hardware non-idealities, temperature drift and aging. These errors can result in a reduced target detection probability or even lead to false detections. According to their appearance in the presented radar system their effects are analyzed with respect to the angular spectrum estimation. A software-based self-calibration algorithm is proposed and evaluated by means of simulations and measurements.
