An Inverse Theory Approach to Incoherent Scatter Drift and Temperature Estimation at the Jicamarca Radio Observatory
… applying this technique to data obtained at the Jicamarca Radio Observatory we have discovered the existence of a westward traveling post sunset vortex which we report in this thesis. In an effort to improve our understanding of the width parameter of the incoherent scatter signal spectrum, we …

Calibration of Jicamarca radar using F-region incoherent scatter for measurements of D-region backscatter RCS
… of mesospheric radar echoes observed at the Jicamarca Radio Observatory in Perú. Radar system calibration is accomplished by simulating the propagation of transmitted and backscattered radio waves through the ionosphere and comparing the simulated power returns to the measurements. The …

Stratospheric scattering of radio waves and the Jicamarca radio telescope
… and mechanisms of stratospheric scattering of radio waves is discussed. The equipment and procedures used in previous experiments at the Jicamarca Radio Observatory are examined in detail, and are found to require modification in some cases. The theory of phased arrays is presented, and the …

Spectral processing and wind estimation with Jicamarca mesospheric radar data
… radar measurement of the mesosphere above the Jicamarca Radio Observatory in the 1970s, advancement in computing has allowed for increasingly complex processing on increasingly large sets of data. These advances have allowed for more accurate processing techniques to be applied to more data …

Investigation of Radar Interferometric Techniques With Application to the Atmosphere
… demonstrated with the spread-F data collected at Jicamarca Radio Observatory, located near Lima, Peru. The zonal and vertical components of the drift velocity of distinct irregularity patches within the radar field of view are estimated using a combination of Doppler and image evolution …

Solar flare effects observed over Jicamarca during MST-ISR experiments
A study of solar flare effects observed at the Jicamarca Radio Observatory (JRO) will be presented. The observations were made while the Jicamarca radar was conducting combined observations in mesosphere-stratosphere-troposphere (MST) and incoherent scatter radar (ISR) modes. Combined MST-ISR …

Study of waves observed in the equatorial ionospheric valley region using Jicamarca ISR and VIPIR ionosonde
… radar) data were taken concurrently at Jicamarca during campaigns of January, April, June, and July 2015, January 2016, and most recently April 2017 to bring more insight into the state and dynamics of the ionospheric E-F valley region and the 150-km radar echoes detected from this …

Study of Coulomb collisions and magneto-ionic propagation effects on incoherent scatter radar measurements at Jicamarca
… of the equatorial ionosphere carried out at the Jicamarca Radio Observatory (Lima, Peru) using antenna beams pointed perpendicular to the Earth's magnetic field B. A Monte Carlo procedure based on the simulation of charged particle trajectories in a magnetized plasma (with suppressed collective …
