Terahertz Radar: Piercing the Veil on Stealth, Space Debris, and the Battlefield

For decades, dominance over the electromagnetic spectrum has defined superiority in defense and security. Microwave radars have enabled long-range detection, while infrared sensors have tracked heat signatures. Yet, between these two lies a little-explored region of the spectrum—the terahertz (THz) band. Occupying the frequencies between 0.3 and 3 THz, this “terahertz gap” is now being…
