Spectral characteristics of the MST radar returns [PDF]

open access: yes, 1983
The salient features of the spectra of atmospheric returns due to random refractivity fluctuations in the Mesosphere, Stratosphere, Troposphere MST region are reviewed. The nonhomogeneous layered structure of turbulence is often evident as multiple peaks

3-D Micro-Motion Features Estimation of Smooth Symmetric Nutating Cone Based on Monostatic Radar

open access: yesRemote Sensing
Micro-motion features of targets, such as nutation and coning, play a crucial role in radar-based target recognition and classification. This paper addresses the challenge of extracting three-dimensional micro-motion parameters from smooth symmetric ...

Development of a networked photonic‐enabled staring radar testbed for urban surveillance

open access: yesIET Radar, Sonar & Navigation
Urban surveillance of slow‐moving small targets such as drones and birds in low to medium airspace using radar presents significant challenges. Detecting, locating and identifying such low observable targets in strong clutter requires both innovation in ...

Signal Processing for Radar with Array Antennas and for Radar with Micro-Doppler Measurements

open access: yes, 2017
Radar (RAdio Detection And Ranging) uses radio waves to detect the presence of a target and measure its position and other properties. This sensor has found many civilian and military applications due to advantages such as possible large surveillance areas and operation day and night and in all weather.
