Large multistatic mm-wave imaging systems have recently been developed and proved to be efficient for security applications. This work analyzes the effects caused by temperature changes on the imaging performance of a state-of-the-art system. The temperature dependent phase drift of a single measurement channel is characterized. A linearized model for the phase drifts in the RF channels is thus derived...
Active millimeter-wave imaging systems are increasingly utilized in security, medical and industrial applications. At E-Band frequencies, such systems integrate more than three thousand antennas on 2 m × 1 m aperture. Commercial success of those systems requires cost efficient but precise manufacturing technologies to build highly integrated modular mm-wave front ends. Here, a module for a new sparse...
