Millimeter-wave radar for vital signs sensing
SPIE Proceedings, 2009In this paper, we will describe the development of a 228 GHz heterodyne radar system as a vital signs sensing monitor that can remotely measure respiration and heart rates from distances of 1 to 50 meters. We will discuss the design of the radar system along with several studies of its performance.

Millimeter Wave Radar Technology
2020Radar is the abbreviation of ‘Radio Detection and Ranging’. It means to detect and estimate distances via the electromagnetic waves. The millimeter wave is an electromagnetic wave that lies between the infrared light wave and the microwave frequency band. Different classification methods are applied on the different classes of the millimeter wave radar.

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.

A millimeter-wave radar for train application
Proceedings of the IEEE International Vehicle Electronics Conference (IVEC'99) (Cat. No.99EX257), 2003A millimeter-wave radar using a spread spectrum technique for train applications has been developed in the 60 GHz band. This radar measures the distance, velocity, azimuth angle, and the magnitude of received signal of each target. The methods for detection are described in this paper. In the experiment, the radar detected the linear shape of trains.
