Prototype solid-state vehicle radar has resolution and range

A team from the Université Côte d’Azur has addressed some of the challenges of automotive lidar, using an acousto-optic modulator, a metasurface deflector and, to improve range and signal to noise ratio, a technique borrowed from telecommunication. Vehicle lidar sends out pulses and measures time-of-flight for returned pulses to determine range. These pulses are sent ...
