Abstract
The techniques of this disclosure enable lidar systems to operate as fast-scanning FMCW lidar systems. The fast-scanning lidar system alternates chirp patterns frame by frame as a way to increase scanning speed, without adding additional hardware. Each consecutive pair of frames includes a frame with a long chirp pattern with multiple chirps and a frame with a short chirp pattern with as few as a single chirp, which is derived from the long chirp pattern assuming a constant object velocity between frames. The chirp pattern applied to each pixel is consistent within each frame but different from one frame to the next. The combined duration of two consecutive frames is less than the combined duration of two consecutive frames of a traditional FMCW lidar system that uses the same chirp pattern from one frame to the next. The shorter duration increases frame rate, scanning speed, or overall throughput of the fast-scanning lidar system.
