First-Order Observation Modeling of Reference--Background Residuals in Single-Snapshot FDA-MIMO-GPR
Yisu Yan, Jifeng Guo
This paper develops a first-order observation model for reference--background mismatch in single-snapshot frequency-diverse array multiple-input multiple-output ground-penetrating…
Weak-Fluctuation-Induced Clutter Covariance and Subspace Structure in Single-Snapshot FDA-MIMO GPR
Yisu Yan, Jifeng Guo
Weak constitutive fluctuations in dispersive subsurface media can induce distributed clutter that reshapes the observation structure of ground-penetrating radar (GPR). This paper a…
Medium-Induced Cross-Frequency Clutter Structure in Single-Snapshot FDA-MIMO-GPR With a Weak-Dispersion Criterion
Yisu Yan, Jifeng Guo
This paper investigates the cross-frequency structure of background clutter induced by random dispersive media in single-snapshot FDA-MIMO-GPR. Representative media are modeled by…
Linking Dispersive-Medium Uncertainty to Clutter Analysis in Single-Snapshot FDA-MIMO-GPR
Yisu Yan, Jifeng Guo
Single-snapshot FDA-MIMO-GPR requires clutter models that account for dispersive-medium uncertainty, yet the statistical link between complex-medium characterization and clutter co…
