PULSE RADAR DISTANCE MEASURING DEVICE AND DISTANCE MEASURING ALGORITHM OF THE SAME

PROBLEM TO BE SOLVED: To provide a pulse radar distance measuring device and a distance measuring algorithm that accurately detect a distance between an object and the pulse radar distance measuring device, and detect a fine oscillation amplitude of the object.SOLUTION: The pulse radar distance measuring device includes: a radio frequency pulse generator; a radio frequency filter; a radio frequency switch; and a transceiver antenna. The radio frequency pulse generator generates a pulse signal, and the radio frequency filter receives the pulse signal and generates a high-pass filter signal including a radio frequency pulse reference signal. The radio frequency switch controls an output of the radio frequency pulse reference signal. The transceiver antenna transmits the radio frequency pulse reference signal. The radio frequency pulse reference signal comes into contact with an object and generates a feedback signal, and the transceiver antenna receives the feedback signal. A distance measuring algorithm is configured to: perform a process analysis of a signal acquired by the pulse radar distance measuring device; and calculate a distance between the object and the pulse radar distance measuring device, using polynomial interpolation.
