Abstract
The present invention relates to a radar unit and provides a radar angle correction method for correcting an error in a radar angle caused by the front cover of an antenna. The radar angle correction method comprises the steps of: measuring a peak power of a beam received from a reference target at each of a plurality of radar angles; plotting a theoretical quadratic curve whose beam width corresponds to a value specified for the radar and whose peak indicates an average of peak values; adopting a difference between a theoretical value indicated by the theoretical quadratic curve and a received beam power as a correction value with which the received beam is corrected; and subtracting the correction value from the received beam power.
