A radar control device is provided, which includes a signal generating module configured to generate a transmission pattern signal comprised of at least one kind of pulse signal that is set among pulse signals including first and second pulse signals, a transmitter configured to externally transmit the transmission pattern signal via a radar antenna, a detector configured to detect transmission power of each pulse signal included in the transmission pattern signal, and a processing circuit configured to control, when the transmission pattern signal includes the second pulse signal, the transmission power of the transmission pattern signal by using a control value calculated based on the transmission power of the second pulse signal, and control, when the transmission pattern signal consists of the first signal, the transmission power of the first pulse signal by using a control value previously used for controlling the transmission power of the second pulse signal.
