    • In order to provide the method and the device for distance measurement by pulse radar that securely eliminates the false echo from the distance over the detectable limit determined by the pulse generation cycle, the pulse radar comprises the pulse signal sending unit that generates the pulse signals with different cycles at OSC 9a˜9c, switches to the predetermined intervals by OSC switch 10, and sends the pulse signal to targets, the reflected signal receiving unit that receives the reflected signals and stores the data in the RAM 25, the reflected signal data acquisition unit that obtains the data of each reflected signal, and the reflected signal identification unit that compares the intensity of the reflected signals obtained at the same lag time point during a certain time period after sending the pulse signal for reference and identifies the reflected signals of the sent pulse signal for reference.
