Abstract: The present invention relates to a high precision pulse Doppler radar and a method for detecting a target using the same. According to the present invention, provided is a method for detecting a target using a high precision pulse Doppler radar, including the steps of: transmitting a narrow band pulse signal to a target, and receiving the narrow band pulse signal reflected from the target; searching a range cell having a Doppler power equal to or over a threshold among total range cells constituting the received narrow band pulse signal; transmitting an ultrawide band pulse signal to the target and receiving the ultrawide band pulse signal reflected from the target; setting partial range cells corresponding to the position of the searched range cell among total range cells constituting the received ultrawide band pulse signal as an interested range cell; and estimating a distance or a speed of the target by using at least one range cell among the interested range cells in the received ultrawide band pulse signal. According to the high precision pulse Doppler radar and the method for searching a target using the same, a limited memory can be used efficiently and distance precision can be increased, according as the approximate position of the determined range cell is set as an interested range cell by using the narrow band pulse signal.
