2026-07-29 Differential-Frequency Resonance Radar Analysis Simulation Code and dataset doi:10.57760/sciencedb.space.03806 en This dataset contains the MATLAB simulation code and example outputs. The code implements an end-to-end signal-level simulator covering: (1)Pierson–Moskowitz stochastic sea surface generation, (2) tilted-Bragg scattering with modulation transfer function, (3) dual-frequency differential echo synthesis, (4) Welch  periodogram slow-time spectral estimation, (5) resonance peak detection and signal-to-noise ratio (SNR) analysis, and (6) wave slope spectrum inversion. Example output files include the sea surface realisation , slow-time power spectra at five target wavelengths , theoretical vs. simulated peak position and SNR comparison  across 50–500 m , SNR parameter sweeps versus footprint size and dwell time , and the retrieved wave slope spectrum compared to the input Pierson–Moskowitz spectrum . The dataset is provided in both MATLAB (.mat) and platform-independent CSV format. differential-frequency; wave spectrum; remote sensing 李金涛 EMBARGO https://api.github.com/licenses/cc0-1.0 dataset Science Data Bank
