FMWC radar for breath detection [PDF]
2016 Progress in Electromagnetic Research Symposium (PIERS), 2016 We report on the experimental demonstration of an FMCW radar operating in the 25.7–26.6 GHz range with a repetition rate of 500 sweeps per second. The radar is able to track the breathing rate of an adult human from a distance of 1 meter. The experiments have utilized a 50 second recording window to accurately track the breathing rate.

Performance Tradeoffs of Joint Radar-Communication Networks
, 2018 This letter considers a network where nodes share a wireless channel to work in turn as pulse radars for target detection and as transmitters for data exchange. Radar detection range and network throughput are studied using stochastic geometry tools.

Science, 1966 The tropopause has been detected by ultrasensitive, narrow-beam, microwave (10.7-centimeter) and ultrahigh-frequency (71.5-cm) radars. Its reflectivity is consistent with that expected theoretically for a refractively turbulent medium. Indications are that the layer is also mechanically turbulent, and that electromagnetic scatter techniques may be used

Periscope detection radar [PDF]
Proceedings International Radar Conference, 2002 The periscope detection problem is described. An advanced simulation model is developed which allows the performance of advanced periscope detection radars to be determined. An advanced system employing three-dimensional filters and distribution-free CFAR is postulated.
