Technology Description

The Multi-Tone Continuous Wave (MTCW) Lidar is an innovative technology that utilizes multiple radio frequency (RF) tones to emit a continuous wave signal, which, upon reflection from a target, enables the determination of the target's distance and speed. This method surpasses traditional LIDAR and RADAR techniques by eliminating the need for consecutive measurements and complex frequency or phase scans, facilitating faster, more accurate, and robust remote sensing capabilities
