Abstract

Provided is a pulse radar device including: a TX unit configured to emit a TX pulse according to a single TX clock signal; a multiple-RX units configured to receive echo pulses received through a plurality of RX antennas according to multiple RX clock signals; a pulse radar driving unit configured to generate the single TX clock signal and the multiple RX clock signals using a reference clock signal. The pulse radar driving unit provides the single TX clock signal and the multiple RX clock signals for the TX unit and the multiple-RX unit. The pulse radar driving unit adjusts an RX clock-to-clock delay that is the delay between the multiple RX clock signals so as to adjust a directivity of the multiple-RX unit, and a TX-to-RX delay between the single TX clock signal and the multiple RX clocks signals so as to adjust a detection range.
