Abstract:
This thesis describes the system integration and newest capabilities of Penn State All-Sky Radar Interferometry System (PARIS). This instrument is located near Penn State campus, at the Rock Springs Radio Space Observatory. This radar is part of a sensor network that is being implemented by Penn State Advanced Signal Processing and Instrumentation Research Laboratory (ASPIRL), that aims to study meteors and field aligned irregularities. This sensor network includes a Cognitive Interferometry Radar Imager (CIRI-PSU), a Penn State Ionospheric Sounder for Chirp Observations (PISCO), and CIRI-Andes, installed in Huancayo - Peru. Earlier prototypes of PARIS included only one receiving channel, operating at 49.8MHz. This thesis presents the implementation of five-receiver channels, operating at 40 MHz. Changes in frequency from 49.8 MHz to 40 MHz, performed on PARIS were implemented due to the interference caused to VHF HAM radio bands, especially the 6m band (50 MHz). This thesis also describes important changes made to the antennas, the transmitter, different signal conditioning stages, and preliminary echoes obtained with the newest version of PARIS.
