Resumen

The Jicamarca-Augmented Radar for Geospace and Upper Atmosphere Studies (J-ARGUS) is a project designed to expand the observational capabilities of the 50 MHz radar at the Jicamarca Radio Observatory (JRO) by transforming it into a tristatic system. This will be achieved by the deployment of two receive-only stations, located approximately 170 km east of Jicamarca, in Huancayo, and about 50 km to the south of Jicamarca, in Santa Maria, Lima. The construction of each station is based on the Long Wavelength Array (LWA) system, which consists of 256 cross-dipole antennas that operate over a broad frequency range (3-88 MHz) and feature electronically steerable beams. © USNC-URSI NRSM 2026.All rights reserved.
