The long-term goal of this research was to develop surrogate roadside grass samples that have representative spectral characteristics of the real roadside grass as measured by automotive LIDAR. The results from this study indicate that LiDAR operation conditions can be mimicked in a lab setup with an ASD spectrometer. ...This paper studied the spectral features of various kinds of grasses as well as determined the reflectance range of these grass types in different measurement conditions with LiDAR. The long-term goal of this research was to develop surrogate roadside grass samples that have representative spectral characteristics of the real roadside grass as measured by automotive LIDAR.

The surrogate grass should be similar to representative real grass in color, LIDAR characteristics, and Radar characteristics. This paper provides the 24 GHz and 77 GHz radar characteristic specifications of surrogate grass.
