An investigation of scattering mechanisms and dynamics in PMSE using coherent radar imaging
In this work, coherent radar imaging (CRI) was implemented using the ESrange RADar (ESRAD) system in Kiruna, Sweden (67:88 ◦ N, 21:10 ◦ E) in the summer of 1998. For the 9rst time, horizontalExpand

Aspect sensitivity measurements of polar mesosphere summer echoes using coherent radar imaging
The Esrange VHF radar (ESRAD), located in northern Sweden (67.88 N, 21.10 E), has been used to in- vestigate polar mesosphere summer echoes (PMSE). During July and August of 1998, coherent radarExpand

On the relationship between aspect sensitivity and spatial interferometric in-beam incidence angles
Abstract Using data from the Middle and Upper Atmosphere Radar, we present a study of the subtle characteristics of the echo power distribution caused by aspect sensitivity at VHF wavelengths. ThisExpand

Optimized NLFM pulse compression waveforms for high-sensitivity radar observations
TLDR
In order to provide adequate sensitivity in low-power radar systems, pulse compression has been used for decades in military applications, and more recently, weather radar. Expand

Methods for Evaluating the Temperature Structure-Function Parameter Using Unmanned Aerial Systems and Large-Eddy Simulation
Small-scale turbulent fluctuations of temperature are known to affect the propagation of both electromagnetic and acoustic waves. Within the inertial-subrange scale, where the turbulence is locallyExpand
