Concurrent firing LIDAR for self-driving car

We proposed a LIDAR that changes the measurement strategy from a sequential emission and measuring method to a concurrent. The proposed LIDAR consisted of 128 output channels in one vertical line in the measurement direction and concurrently measured the distance for each. This emitted 128 laser pulse streams encoded by carrier-hopping prime code (CHPC) technology with identification and checksum. When the reflected pulse stream was received and decoded, the emission channel could be recognized. This information was used to estimate the time when the laser pulse stream was emitted and calculate the distance to the object reflecting the laser. Extensive simulations indicated that the proposed LIDAR could provide self-driving car with good distance images to recognize the environment ahead.
