Recently, studies and developments of Collision Warning System(CWS)have attracted widely a particular attention among various wave applications at 60 GHz frequency band. Major performance of the CWS is given by the maximum detection range, the minimum detectable width and accuracy of detection distance. Since the maximum detection range and the minimum detectabe width depend on a size of a target, it is important to know Radar Cross Section(RCS)of the target. RCS data should be measured so-called far field condition(greater than a few fundreds meters), while CWS is usually used in the range of 20-100m. Therefore, a measurement of the reflection characteristics in shorter distance should be necessarily known. In this study, we present reflection characteristics of a medium size truck and a passenger car measured in open field at 60 GHz frequency. It is concludingly described that the reflection characteristics of the passenger car and the medium size truck are 13-18 dBm^2 and 15-32 dBm^2, respectively, for a case of horizontal polarization.
