摘要： An imaging device includes an antenna configured to transmit millimeter waves, a connector adapted to connect a radio frequency (RF) signal source with the imaging device and a signal path connected between the connector and the antenna. A nonlinear transmission line (NLTL)-based frequency multiplier is arranged along the signal path to receive an RF signal from the RF signal source and increase a frequency of the RF signal to millimeter frequency to produce a millimeter wave. A NLTL-based variable delay line is arranged along the signal path between the NLTL-based frequency multiplier and the antenna. A time delay of an NLTL of the NLTL-base variable delay line is variable to steer a beam of the millimeter wave in at least one dimension as the millimeter wave is transmitted by the antenna. A receiver processes a return signal received in response to the millimeter wave.
