Design of a Wide-Band Beacon-Receiver Array for Marine Atmospheric Boundary Layer Measurements
Abstract
Design of a Wide-Band Beacon-Receiver Array for Marine Atmospheric Boundary Layer MeasurementsA project to design a wideband version of the existing X-band Beacon-Receiver Array(XBBR) is proposed, with the goal of producing an improved system for monitoring the at-seapropagation environment. The XBBR system developed under previous support uses multipletransmit beacons combined with multiple receivers to observe a ~matrix~ of propagation pathsthrough the marine atmospheric boundary layer (MABL). The systems operates only within anarrow band of frequencies near 11 GHz; the transmissions of individual beacons are shiftedslightly in frequency to enable them to be distinguished at each receiver. Studies using bothmeasured and simulated datasets with the existing XBBR system have shown the utility of thesystem for retrieving a single ~duct height~ parameter describing MABL conditions. Under relatedefforts, the CASPER project is deploying an ultrawideband transmit/receive system that utilizesonly a single pair of transmit and receive antennas. While this system captures multiple-frequencyproperties of the MABL, it fails to characterize variations with height. The ability of both theXBBR and CASPER systems to monitor more complex propagation scenarios is limited by theiruse of a single frequency only or of a single pair of transmit and receive antennas, respectively.
