Pulse radar apparatus and operating method thereof

A pulse radar apparatus that detects a position and a motion of a target comprising:

• a clock signal generator configured to output a transmission clock signal and a reception clock signal;
• a transmitter configured to generate a first signal, based on the transmission clock signal;
• a receiver configured to receive an echo signal corresponding to the first signal, to receive the reception clock signal, and to generate a second signal, based on the echo signal and the reception clock signal;
• and
• a signal processor configured to convert the second signal into a digital signal and to analyze the digital signal,
• wherein the clock signal generator controls a transmission-to-reception clock delay between the transmission clock signal and the reception clock signal, and generates a synchronization signal representing a change in the transmission-to-reception clock delay,
• wherein the signal processor converts the digital signal into a representative value using the synchronization signal, and analyzes the second signal using the representative value, and
• wherein 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.
