Abstract: Disclosed are a pulse radar apparatus and an operating method of the pulse radar apparatus, the pulse radar apparatus including a transmitter configured to receive a reference signal as a transmission clock signal, and transmit a transmission pulse to an object based on the transmission clock signal, a negative feedback loop configured to delay the reference signal and output the delayed reference signal as a reception clock signal, and a receiver configured to restore, based on the reception clock signal, a reflection pulse received in response to the transmission pulse being reflected from the object, wherein the negative feedback loop is configured to generate a delay control signal using the reference signal and a predetermined waveform signal generated by a waveform generator, delay the reference signal based on the delay control signal, and adjust the delay control signal by controlling the waveform generator to change the predetermined waveform signal.

Abstract: Disclosed is an entropy generation apparatus, which includes a detector that detects particles emitted from the radiation source to generate a detection signal; a preamplifier that amplifies the detection signal to generate an amplified signal; a filter that filters the amplified signal to generate a filtered signal; and a comparator that generates a pulse based on a result of comparing the filtered signal with a threshold value.
