The overall flowchart of the proposed physics-based component-wise simulation framework. The workflow consists of 3 stages: (A) semantic scene construction, where the radar footprint is discretized and water objects are semantically labeled using spatial priors; (B) forward modeling, where signal entanglement is simulated by independently integrating scattering contributions from the main channel and interfering bodies (lakes/floodplains) and superimposing them with system responses; (C) parameter inversion, utilizing separable nonlinear least squares (SNLS) to fit the simulated waveform to the observed Sentinel-3 synthetic-aperture radar (SAR) waveform.
