Abstract: Disclosed is an ultra-wide band (UWB) radar device including a first antenna circuit including a first transmission circuit, a first reception circuit, a first oscillator that supplies a first clock signal to the first transmission circuit and the first reception circuit, and a first frequency counter, a second antenna circuit including a second transmission circuit, a second reception circuit, a second oscillator that supplies a second clock signal to the second transmission circuit and the second reception circuit, and a second frequency counter, and a controller that detects the target. The controller corrects a frequency error between the first clock signal and the second clock signal and compensates for a synchronization error between the first antenna circuit and the second antenna circuit.
