Abstract: Devices, systems, and methods for remote detection and ranging are described. In an embodiment, a remote sensing method includes obtaining data points that are spatially distributed and have respective intensity values, by performing a remote detection and ranging operation, determining a spatial autocorrelation of a set of data points, out of the data points, based on a difference in distances between data points in the data points, determining an intensity weight multiplier based on a reference intensity value of the data points and an average intensity value of the data points, and determining a quality score of the set of data points by applying the intensity weight multiplier to the spatial autocorrelation of the set of data points; and identifying, based on the quality score, whether the set of data points includes one or more data points that are created by a noise source.
