A concept of the extremely short-range radar is presented. The formula of the operating distance is derived and a novel Doppler-based extremely short-range radar in the 3 millimeter wave band was developed. The result of test indicates that the radar has the advantages of simple structure, low cost and high accuracy in the range determination within the distance from less than one meter to several meters.
