Millimeter-wave radar systems for biometric applications
SPIE Proceedings, 2009Millimeter-wave and terahertz radar systems can play an important role in multimodal layered sensing systems targeted at measuring both physiological and behavioral biometric data for security and medical applications. We will describe a 228 GHz heterodyne radar system that is capable of measuring respiration rates at standoff distances of up to 50 ...

Motion Monitoring With A Millimeter Wave Radar Sensor
27th European Microwave Conference and Exhibition, 1997An existing 94 GHz pulse radar system for autonomous mobile robots has been extended by a CW Doppler unit for fast motion monitoring. The extension is set up with low cost components and works independently from the pulse system. Until now the capabilities for motion detection has been validated in several environments.

Millimeter-Wave Radar for Rescue Helicopters
2006 9th International Conference on Control, Automation, Robotics and Vision, 2006A collision avoidance and warning system for civil helicopters in Japan has been developed. A real-time warning method was applied using an image fused from a coloured video, an IR sensor data and mm-wave radar measurements. This paper focuses on the FM-CW mm-wave radar sensor and the associated antennas, working at 94 GHz.

On energy potential of millimeter-wave radar
Third International Kharkov Symposium 'Physics and Engineering of Millimeter and Submillimeter Waves'. MSMW'98. Symposium Proceedings (Cat. No.98EX119), 2002One of the most serious problems of a short-pulse millimeter (MM) wave radar is deficit of its energy potential. The radar range upper limit of about a few kilometers is caused mostly by two factors: (1) low energy of transmitting signal pulses restricted by generator overheating or breakdown of waveguiding structures; and (2) decreasing of signal ...

A Near-Millimeter Wave interferometric radar
2013 IEEE Radar Conference (RadarCon13), 2013Due to the paucity of high-power sources along with strong electromagnetic absorption by water vapor at frequencies between ~100 GHz and ~10 THz, there are very few radar systems operating in the terahertz range of the spectrum. Source technology, however, is improving, thus facilitating radar systems operating in this gap.

SPIE Proceedings, 1996
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.
