A doppler radar device having comparing means 142 for comparing the level of pulse signal to be transmitted, sampled through a burst gate, with a predetermined threshold value and search means 143 for changing a set position of the gate, wherein a timing of oscillating the pulse signal is monitored and tracked to fix "range 0" by shifting a timing for triggering transmission of the pulse signal in consideration of a deviation of the timing of oscillating the pulse signal and a jitter value.
