An IQ-Level Benchmark Dataset and Interference Suppression Comparison Demo for Phased-Array Dual-Polarization Weather Radar<p dir="ltr"><b>Authors:</b> Zhihuo Xu and Yuexia Wang<br><b>Revised benchmark release:</b> 02 October 2026<br><b>Comparison program version:</b> 3.0.0</p><h2 dir="ltr">Overview</h2><p dir="ltr">This repository provides a self-contained IQ-level benchmark dataset and a reproducible comparison program for radio-frequency interference (RFI) suppression in phased-array dual-polarization weather radar.</p><p dir="ltr">Each released NetCDF result is self-contained: it stores the Ground-truth IQ, the corresponding Observed-RFI IQ, and the Recovered IQ produced by that method.

The Ground-truth and Observed-RFI IQ are duplicated across the four method files so that every result can be inspected independently while still supporting a common-input comparison.</p><p dir="ltr">The current release contains four successive suppression models:</p><ol><li><b>PolStatJoint</b></li><li><b>PolPhaseAware</b></li><li><b>PolMomentV1</b></li><li><b>PolMomentV2</b></li></ol><p dir="ltr">and three interference scenarios:</p><ul><li><b>CW</b> (<code>cw_only</code>)</li><li><b>LFM</b> (<code>lfm_only</code>)</li><li><b>LFM+CW</b> (<code>lfm_plus_cw</code>)</li></ul><p dir="ltr">Each method/scenario result is stored in a self-contained <code>recovered_full360.nc</code> file containing the Ground-truth IQ, Observed-RFI IQ, Recovered IQ, radar geometry, interference mask, and Level-II fields needed by the comparison workflow. </p><p dir="ltr">For each scenario, the PolStatJoint <code>recovered_full360.nc</code> is used as the canonical source of Ground-truth IQ, Observed-RFI IQ, the interference-ray mask, azimuth/range coordinates, radar metadata, and Ground-truth/Observed Level-II fields.
