Randomized trial evaluates diffraction's impact on radar measurements of wave profiles, highlighting errors in estimates.

The aim is to assess how diffraction affects radar illumination of sea wave profiles, particularly in shadowed areas.
Used path integral methods to calculate diffraction effects on X band radar illumination.
Compared ray optics estimates with full diffraction calculations in shadowed wave regions.
Diffraction significantly alters the illumination profile of the sea surface in wave shadowed areas.
Ray optics approach leads to substantial inaccuracies in illumination intensity estimates.

Janssen et al. (2026) studied this question.
