FROM RF TO BITS WITH SYNTHETIC BEAMFORMING

ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California / A Synthetic Beamforming antenna was built for Airborne Telemetry. Low-Noise Block-converters
translated RF to IF suitable for direct analog-to-digital conversion. Then all telemetry
functions were performed digitally via parallel FPGAs for 10 independent sources. Monopulse
tracking and optimal diversity combination was performed using 4 antenna quadrants at two
orthogonal polarizations. Novel estimation approaches drove digital demodulation, symbol- and
bit- synchronization. Final telemetry outputs include: digital, analog (video), and analog IF (e.g.,
for downlink relay). This program has incubated several concepts that we believe have the
combined potential to significantly improve the future of telemetry.
