Abstract
The present disclosure relates to an antenna return loss compensation apparatus and method of a radar and a radar apparatus using the same. The antenna return loss compensation apparatus may include a compensation information calculator configured to calculate return loss compensation information for compensating for a frequency-band based antenna return loss, and a return loss compensator configured to apply return loss compensation information to a reception signal that is reflected from an object and is received, so as to generate a final reception signal, may calculate and store, in advance, compensation information for a return loss occurring in the antenna, may perform compensation associated with the magnitude of a reception signal when measurement is performed using the radar, so that the reception signal has the same magnitude, whereby a radar's performance deterioration attributable to the return loss of the antenna may be minimized.
