MIMO Radar

Abstract

We show the concept of multiple-input multiple-output (MIMO) radar and introduce practical applications, which include ground based synthetic aperture radar (GB-SAR) and ground penetrating radar (GPR). As an example, a 17 GHz MIMO GB-SAR system to be used for landslide monitoring and infrastructure measurement is described. We also show that a MIMO GPR system “Yakumo” can achieve dense three-dimensional (3D) subsurface imaging compared to conventional GPR. We also explain that MIMO GPR can be used for common midpoint (CMP) measurement, which can be used for the estimation of the vertical profile of EM velocity, which is related to soil moisture.
