Fog Detection Using Airport Radar [PDF]
2006 International Radar Symposium, 2006 Fog is a significant factor affecting the Air Traffic Control (ATC). Significant limitations of the airport capacity are due to fog that causes the reduction of the visibility (Runway Visual Range, RVR). Today METAR (Meteorological Aviation Report) and forecasts TAF (Terminal Aerodrome Forecast) are only available to estimate the visibility variations,

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.

Simulation of hailstorm event using Mesoscale Model MM5 with modified cloud microphysics scheme [PDF]
Annales Geophysicae, 2008 Mesoscale model MM5 (Version 3.5) with some modifications in the cloud microphysics scheme of Schultz (1995), has been used to simulate two hailstorm events over Gangetic Plain of West Bengal, India. While the first event occurred on 12 March 2003 and

A novel approach to robust radar detection of range-spread targets [PDF]
Signal Processing, 2019 This paper proposes a novel approach to robust radar detection of range-spread targets embedded in Gaussian noise with unknown covariance matrix. The idea is to model the useful target echo in each range cell as the sum of a coherent signal plus a random

Study on Quantum Radar Detection Probability Based on Flying-Wing Stealth Aircraft
Sensors, 2022 The development of quantum radar technology presents a challenge to stealth targets, so it is necessary to study the quantum detection probability. In this study, an analytical expression of the quantum radar cross section (QRCS) for complex targets is ...

Adaptive Radar Detection of Dim Moving Targets in Presence of Range Migration [PDF]
IEEE Signal Processing Letters, 2019 This letter addresses adaptive radar detection of dim moving targets. To circumvent range migration, the detection problem is formulated as a multiple hypothesis test and solved applying model order selection rules which allow to estimate the “position ...
