An ultra high resolution FMCW radar [PDF]

, 1992
Bibliography: leaves 127-128.There is a great need for real-time non-intrusive measurements in industry. A short-range radar system can be used to make these measurements. A standard requirement for these type of applications is high resolution.

The radar signature of the Wind Lens: a less disruptive wind turbine? [PDF]

, 2012
We study the radar signature of a new type of wind turbine, named the Wind Lens. This design includes a flanged shroud around the turbine which concentrates the wind flow past the turbine blades and hence improves the efficiency.

UAV-Carried Multi-Sensor System for Detecting People and Monitoring Vital Signs in Open-Field Rescue Scenarios

IEEE Access
In post-disaster situations, emergency services require an efficient method to quickly detect and monitor the vital signs of injured people. In this work, we present a UAV-carried sensor system to locate injured people in open-field rescue scenarios and ...
