Abstract

The LIDAR system includes a first transform component configured to perform a complex mathematical transform on first signals. The LIDAR system also includes a second transform component configured to perform a real mathematical transform on second signals. Electronics are configured to use an output of the first transform component in combination with an output of the second transformation component to generate LIDAR data. A signal level ratio obtained by using the first and the second signals is used to identify a material of an object for which the second signals were reflected signals corresponding to the first signals being incident on the object.
