Specular Reflection Measurements in a Multipath Site at Intermediate-Field Ranges

Reflection coefficient measurements can be performed by using two antennas and a material sample of a known radar cross section. At frequencies in the L-band high-directivity antennas such as horn antennas would have large physical size. In this work, we present a method based on measurements in a multipath site, at intermediate-field ranges with a pair of planar, low-directivity antennas. Our approach was validated by measurements on a rectangular aluminum plate.
