Near-grazing radar backscattering measurements of road surfaces at 222 GHz

7/1/2017    2017 IEEE International Geoscience and Remote Sensing Symposium    Information & Communication, Electronics & Photonics


This paper reports on a set of radar experiments conducted at 222 GHz in support of envisioned application of radars to autonomous vehicles. The measured radar backscatter data of road surfaces at incident angles between 80 and 88o are presented. The polarimetric radar response level from different surfaces encountered in roads and highway environments and the angular dependency are discussed. The results are helpful in developing models for different surfaces and in the design process and assessment of autonomous vehicles sensors.
