FMCW radar

Terahertz research image associated with Guided Reflectometry Imaging Unit Using Millimeter Wave FMCW Radars

FMCW radar transmits a continuously swept frequency and measures the beat signal produced by delayed reflections, enabling distance, thickness, and depth-resolved imaging with compact coherent hardware.

What is terahertz radiation?

Terahertz radiation is electromagnetic energy commonly associated with frequencies around 0.1 to 10 THz, between microwaves and infrared, where many materials reveal distinctive propagation, absorption, and imaging behavior.
