Claim 0:
1. A method for anomaly detection using a light detection and ranging (LIDAR) sensor comprising:
generating a wide-angle laser emission via an optical grating array;
detecting a reflected signal of the wide-angle laser emission, wherein the detected wide-angle laser emission comprises a measured representation;
retrieving a stored detected wide-angle laser emission, wherein the stored detected wide-angle laser emission comprises a baseline representation;
comparing the measured representation to the baseline representation by processing the reflected signal of the wide-angle laser emission by a Fast Fourier algorithm and convolving the processed reflected signal with the retrieved stored detected wide-angle laser emission; and
identifying an anomaly based on the processed signals depicting received power representations unique to the anomaly identified, the identification corresponding to the comparison between a first slope of the baseline representation and a second slope of the measured representation, the anomaly representing an impediment in a travel path.
