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.

Millimeter-wave noise radar tomography
2016 9th International Kharkiv Symposium on Physics and Engineering of Microwaves, Millimeter and Submillimeter Waves (MSMW), 2016SAR tomography based upon MIMO concept with channels time-division is described and some results of its experimental validation using Ka-band ground based noise waveform SAR are presented. Two different linear synthetic apertures have been used for both transmit and receive antennas oriented in vertical and horizontal directions, respectively.

Antenna Concepts for Millimeter-Wave Automotive Radar Sensors
Proceedings of the IEEE, 2012Automotive radars are on the market since 1999, both in the frequency range around 24 GHz as well as 76.5 GHz, with a new frequency band ranging from 77 to 81 GHz intended for medium and short-range sensors. The choice and design of the respective sensor antennas are determined by the requirement for high gain and low loss combined with small size and ...
