Abstract
Systems and methods of simulating an effect of fog on a Light Detection and Ranging (LiDAR) sensor are disclosed. The method includes the steps of determining whether a target is present within the field-of-view (FOV) of the LiDAR sensor, determining a fog probability density function (PDFfog) vs range, modifying, if a target is present within the FOV, the PDFfog to account for the target, calculating a cumulative density function (CDF) for the PDFfog, randomly sampling the CDF to determine a plurality of ranges and additively plotting a predetermined Gaussian distribution centered on each range, and identifying a peak value of the additive plot and reporting the range associated with the peak value as the strongest return of the LiDAR unit.
