1. A radar control device comprising:
a transceiver configured to transmit a transmission signal to the surroundings of a host vehicle and receive a reception signal received by reflecting the transmission signal on an object;
a determiner configured to generate a first range-Doppler map by performing fast Fourier transform (FFT) on the reception signal and generate a second range-Doppler map based on a comparison group including a plurality of preset temporary lateral distances, and determine a correlation coefficient between the first range-Doppler map and the second range-Doppler map; and
an estimator configured to estimate a lateral distance between the host vehicle and the object based on the correlation coefficient.
