Time-Domain Gating Optimization for Stationary Free-Space Radome Measurement

초록

This paper proposes a stationary free-space measurement method that integrates mathematical reference plane calibration and time-domain gating (TDG) optimization for precise S-parameter analysis of multi-layer radomes. The technique eliminates physical sample repositioning and empirical parameter tuning while suppressing alignment errors and noise. X-Ku band validation on a 16-layer SATCOM radome demonstrates measurement deviations of <= 0.3 dB in S-11 and <= 0.2 dB in S-21, with RMS errors below <0.01 across the band. Results establish a robust framework for high-performance radome evaluation in aerospace and satellite communication (SATCOM) applications.
