UWB radar device for correcting frequency error and synchronization error and method of operating the same

An ultra-wide band (UWB) radar device comprising:

• a first antenna circuit including a first transmission circuit configured to transmit a first signal to a target based on a synchronization signal, a first reception circuit configured to generate pieces of first sampling data from the first signal reflected from the target, a first oscillator configured to supply a first clock signal to the first transmission circuit and the first reception circuit, and a first frequency counter configured to obtain first frequency data of the first clock signal;
• a second antenna circuit including a second transmission circuit configured to transmit a second signal to the target based on the synchronization signal, a second reception circuit configured to generate pieces of second sampling data from the second signal reflected from the target, a second oscillator configured to supply a second clock signal to the second transmission circuit and the second reception circuit, and a second frequency counter configured to obtain second frequency data of the second clock signal;
• and
• a controller configured to generate the synchronization signal and to detect the target based on the pieces of first sampling data and the pieces of second sampling data,
• wherein the controller is configured to:
• correct a frequency error between the first clock signal and the second clock signal;
• and
• compensate for a synchronization error between the first antenna circuit and the second antenna circuit.
