The Quanergy system looks like it's doing conventional pulsed time of flight (maybe FMCW, but I don't know). They're operating in a frequency band that lets them put out a lot of power without risking eye safety, which means long range. Pulsed LIDAR is basically limited only by signal to noise, so provided you get some photons back and you know they're 'yours', you can measure long distances.
- deepnotderp 9y agoThe DARPA SWEEPER was also pulsed lidar, and it only had a range of 2 meters. And the problem really isn't the regulations for power output at the wavelength, but rather that the optical phased array itself can't put out the necessary power, regulations notwithstanding.
