India’s Indigenous Surface Wave Over-the-Horizon Radar Nears Field Trials

India’s Ministry of Defence is advancing its Surface Wave Over-the-Horizon (SW-OTH) Radar project into the trial phase, marking a major milestone in indigenous long-range maritime surveillance technology.The system employs high-frequency (HF) surface-wave propagation, allowing radar signals to bend and travel along the curvature of the sea, thereby detecting vessels far beyond the line-of-sight
