Abstract
A new scheme of a pulse-Doppler radar for the effective detection of metal objects in a short range of millimeter waves is presented. An omnidirectional transmitting antenna (TXA) is used to provide full angular coverage while a directional receiving antenna (RXA) collects the coded signals for the determination of range and angle of the arriving signal. A Doppler shift is created by making RXA horizontally rotate along the axis of TXA, which creates a relative velocity between the RXA and the target under detection. It is shown that the system may detect targets as small as 0.2  m2 with a high resolution.
