Microwave scattering experiment on a wave tank: Bistatic setup

To validate models of electromagnetic wave scattering by rough surfaces, a laboratory experimental setup of microwave scattering by a water surface is implemented above a wave tank. This wave tank facility allows to produce controlled waves and, therefore, to acquire signals with known conditions. The previous configuration was monostatic, i.e. with both antennas (the transmitter and the receiver) in the same location, and it therefore enabled to record only the signal backscattered after reflection from the water surface. Very recently, we extended the experimental setup to get a bistatic configuration, with the two antennas in different locations. Measurements are acquired for several angles of incidence and observation and for various conditions of waves. The analysis of measurements permits to study the effect of electromagnetic parameters (frequency, angles of antennas, ...) and hydrodynamic parameters (wave type, height and wavelength, ...).
