Eos, Transactions American Geophysical Union, 1947 Radar photographs of thunderstorms and the Florida hurricane of September 1945 were shown to illustrate structure of those storms (see Fig. 1). The relation between radar echoes and the reflecting material in the storms was discussed. Previous research has shown the intensity of the return radiation, among other things, to be proportional to the number

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.

UWB Radar for Human Being Detection
IEEE Aerospace and Electronic Systems Magazine, 2006 UWB radar for detection and positioning of human beings in complex environment has been developed and manufactured. Novelty of the radar lies in its large operational bandwidth (11.7 GHz at -10 dB level) combined with high time stability. Detection of respiratory movement of a person in laboratory conditions has been demonstrated. Based on experimental

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

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.

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.

Electronics Letters, 1985 In the letter a new adaptive procedure for the detection of a radar target in clutter is described. The procedure is based on the development of linear models for the two hypotheses H0 and H1. Under hypothesis H0, there is no target present, and the received signal is modelled as a regressive process.

Radar Target Detection with CNN
2021 29th European Signal Processing Conference (EUSIPCO), 2021 Target detection is a fundamental radar application that is traditionally carried out by Constant False Alarm Rate (CFAR) detectors. This paper proposes a Convolutional Neural Network (CNN) based detector (RadCNN) to replace the standard CFAR detectors for a typical pulsed Doppler radar.
