Size Determination in Particle Streams Using a Multistatic Dual Frequency Millimeter Wave Radar

A multistatic dual frequency radar operating at 91.5 GHz and 150.3 GHz is designed and utilized to measure particle dimensions in a multidisperse particle stream. From the physical relations a size measurement routine is derived. In a numerical study we then investigate how a multistatic antenna configuration can improve the state-of-the-art method which usually is performed with a monostatic radar. Based on the simulation results, we present the layout of the radar sensor and experimental setup. Finally, measurement results are provided and discussed.
