Define phased-array antenna and RF-system architectures for satellite communication ground stations.
Translate mission, coverage, link-availability, waveform, throughput, and regulatory requirements into aperture, RF front-end, beamforming, calibration, pointing, and tracking specifications.
Develop and maintain end-to-end SATCOM link budgets incorporating measured aperture and RF-chain performance.
Evaluate array architectures and tradeoffs involving aperture size, element spacing, polarization, scan volume, grating lobes, sidelobes, taper efficiency, channel count, beam count, and RF-to-digital partitioning.
Analyze analog, hybrid, and digital beamforming approaches in collaboration with RF and digital implementation teams.
Determine how antenna and RF impairments affect communications performance, including EVM, carrier acquisition, BER/BLER, throughput, spectral compliance, and link availability.
Analyze RF lineups and performance budgets for gain, noise figure, dynamic range, linearity, compression, intermodulation, phase noise, frequency stability, filtering, and isolation.
Define array calibration strategies addressing channel-to-channel amplitude and phase variation, temperature drift, mutual coupling, element failures, polarization error, and scan-dependent behavior.
Develop pointing, acquisition, tracking, beam-management, and handover strategies for operational satellite links.
Model propagation, atmospheric attenuation, polarization loss, interference, multipath, blockage, and other environmental effects relevant to ground-station deployment.
Build Python, MATLAB, or similar models combining array behavior, measured RF performance, propagation, and modem-level metrics.
Plan and execute conducted, chamber, near-field, far-field, over-the-air, and end-to-end communication-link testing.
Lead cross-functional investigations of degraded G/T, EIRP, link margin, EVM, acquisition, tracking, BER, throughput, or spectral performance.
Correlate analytical models and simulations with measured aperture, RF, modem, and operational link data.
Support regulatory submissions, spectrum coordination, partner interface reviews, system acceptance, and operational deployment.
