Abstract: The present disclosure relates to a pulse radar device comprising a memory that includes a first memory and a second memory, each storing a scan vector. The device also includes a clock generator that produces a transmission clock signal and a reception clock signal. The reception clock signal is generated by delaying the transmission clock signal by a clock delay value. Furthermore, the device includes a transmitter that generates a transmission pulse by accepting the transmission clock signal from the clock generator and emits the pulse. Additionally, the device includes a receiver that receives an echo pulse reflected from a target by accepting the reception clock signal from the clock generator. The receiver then calculates the received echo pulse to generate a representative scan vector.

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: 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.
