Abstract An inductino device for directional digit radar uses the antenna to continuously emit the microwave which reflects the signal at its contacting with a moveable article. The reflected signal is detected out the phase different of 90 degree existing in the intermediate frequency separately by two frequency mixers when the reflected signal is passing through the two frequency mixer in the guide wave tube with a quarter wave length distance in between. The forward or backward of the moveable article can cause the lead or behind of phase signal and to send the signal int digital unit crystal processor for identification and the function to be used is calculated out.
