Abstract: Disclosed is a radar device capable of operating in a dual mode, which includes a transmitter that includes a first signal generator that generates a Doppler radar signal and a second signal generator that generates a Frequency Modulated Continuous Wave (FMCW) radar signal, a receiver that receives a reflected signal reflected from a target and converts the reflected signal to a digital signal, a signal processing circuit that processes the digital signal differently depending on the dual mode to output an output signal, a signal analysis circuit that analyzes the output signal, and a controller that controls operations of the transmitter, the receiver, the signal processing circuit, and the signal analysis circuit, and the dual mode includes a first mode in which the first signal generator is activated and a second mode in which the second signal generator is activated.

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.
