Paper Abstract

Recent advances in MMW solid-state technology, combined with state-of-the-art quasi-optical feed elements, have made possible upgrades to an instrumentation radar in the W-band. Mixer diodes capable of cryogenic operation have led to a reduction in the receiver noise figure, and a Gunn-effect diode amplifier has boosted transmit power. Application of Gaussian beam optics has provided a reduction in transmit and receive losses, while increasing transmit/receive isolation and power handling capability. In all, an improvement of almost two orders of magnitude is ought, yielding the capability to provide metric tracking and range-Doppler imaging on a variety of important targets.
