The main objectives of this study were characterizing the radar scattering properties of common highway roadside objects in 24 GHz and 77 GHz bands. So far, we have developed measurement methodology and studied scattering properties of concrete curb and concrete. This paper focused on collecting initial scattering data of roadside objects under stationary. The measurements were conducted at 24 GHz with 1 GHz bandwidth using a commercial software-defined radar (SDR) manufactured by Ancortek. These measurements were mainly conducted for understanding the general scatting strength and measurement setup requirements, and were not for detail characterization of the radar cross section (RCS) properties. We also measured the reflection coefficient of concrete for spaying water. In preparation for fabricating roadside surrogates, we also began to measure the reflectivity of several conductive fabric in our possession to determine if any of them could be suitable for dressing the roadside surrogates for producing similar reflectivity as the surface of selected representative roadside objects.
