Abstract: Disclosed are a pulse radar apparatus that detects a position and a motion of a target, and an operating method thereof. The pulse radar apparatus includes a clock signal generator that outputs a transmission clock signal and a reception clock signal, a transmitter that generates a first signal, a receiver that receives an echo signal and the reception clock signal, and generates a second signal, and a signal processor that converts the second signal into a digital signal and analyzes the digital signal. The clock signal generator controls a transmission-to-reception clock delay, and generates a synchronization signal. The signal processor converts the digital signal into a representative value and analyzes the second signal using the representative value. The representative value is one of an accumulated sum of the digital signal in a time duration between synchronization signals and an average value of the digital signal in the time duration between synchronization signals.

Abstract: Provided is a radar device including a clock generator, a transmitter, and a receiver. The clock generator may output a transmission clock, and output a reception clock after a delay from a time at which the transmission clock is output. The transmitter may include a transmission trigger signal generator to generate a transmission trigger signal based on the transmission clock and an oscillator configured to generate a first signal on the basis of the transmission trigger signal. The first signal and the transmission trigger signal may include a pulse, and a width and a magnitude of the pulse included in the first signal correspond to a width and a magnitude of the pulse included in the transmission trigger signal, respectively. The receiver may be configured to receive an echo signal corresponding to the first signal to generate a second signal based on the reception clock.

Abstract: A radar device according to an embodiment of the inventive concept includes a clock generator, a transmitter, a receiver, and a signal processor. The clock generator outputs the transmission clock, outputs the reception clock at the second time after the delay from the first time when the transmission clock is outputted, and generates the notification signal when the delay has the minimum value. The transmitter emits a transmission signal based on the transmission clock. The receiver receives an echo signal corresponding to the transmission signal, and generates a first signal corresponding to the echo signal based on the reception clock. The signal processor obtains a third time point at which a delay has the minimum value based on the notification signal.
