A millimeter-wave (mmW) imaging device comprises a mmW radar sensor, an auxiliary sensor arrangement, and at least one processor. The mmW radar sensor comprises a transmitter coupled to an antenna arrangement configured to transmit mmW radiation at a target, and a receiver coupled to the antenna arrangement or a separate antenna arrangement configured to receive backscatter radiation from the target. The auxiliary sensor arrangement is configured to detect one or both of relative motion and relative position between the imaging device and the target. A processor of the mmW imaging device is configured to receive data respectively produced by the mmW radar sensor and the auxiliary sensor arrangement during relative movement between the imaging device and the target. The processor or a remote processor is configured to reconstruct a mmW radar image of the target using the received data.
