Popis: | Recently, the investigation of a collision-warning system (CWS) has spurred a growing interest in 60 GHz band applications. The performance of the CWS is examined by the maximum detection range, the minimum detectable width, and the accuracy of the detection distance. It is important to examine the radar cross section (RCS) of the target because the maximum detection range and the minimum detectable width depend on the target size. The measurement of the reflection characteristics under a short distance was examined previously. RCS data should be measured under the far-field condition, where the CWS is usually in the range of 20–100 m. In this study, we examine the reflection characteristics of a truck and a bus under an open field in the 60 GHz band. It is found out that the RCS of the truck and the bus under horizontal polarization are in the range of 15–37 and 12–51 dBm2, respectively. © 2000 John Wiley & Sons, Inc.
