2020 10th International Symposium on Signal, Image, Video and Communications (ISIVC), 2021 In this paper, a study of UWB receivers in terms of detection theory is presented. The UWB radar which is presented in many works previously [1]–[3] has many applications. For road UWB radar application, the receiver based on correlation is the optimum receiver [4]. In fact, it maximizes the probability of detection.

IEEE Access, 2018 The radar echoes of moving targets in a clutter background are extremely weak and their characteristics are complex. A low-observable moving target detection technology has become a key constraint to radar performance, requiring the radar to provide ...

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

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.

Developments in target micro-Doppler signatures analysis : radar imaging, ultrasound and through-the-wall radar [PDF]
, 2013 Target motions, other than the main bulk translation of the target, induce Doppler modulations around the main Doppler shift that form what is commonly called a target micro-Doppler signature.

Animal Lameness Detection With Radar Sensing [PDF]
IEEE Geoscience and Remote Sensing Letters, 2018 Lameness is a significant problem for performance horses and farmed animals, with severe impact on animal welfare and treatment costs. Lameness is commonly diagnosed through subjective scoring methods performed by trained veterinary clinicians, but automatic methods using suitable sensors would improve efficiency and reliability.
