Abstract: A LiDAR echo signal processing method is disclosed. The method includes: receiving an echo signal reflected by a to-be-detected object, where the echo signal includes multidimensional signal emission angles; buffering the echo signal based on the multidimensional signal emission angles to obtain buffered signals; when the number of buffered signals reaches a preset buffering number, extracting a target signal corresponding to a preset neighborhood window from the buffered signals; and performing non-coherent integration on the target signal and outputting the integrated target signal.
