Reconfigurable, Low-Cost Monostatic Ultra-Wide Band Radar

An original monostatic UWB FMCW radar architecture has been developed for GPR applications. The radiation system is composed of a single antenna associated with a double switching configuration to minimize the compactness of the antenna system while ensuring a sufficient dynamic range. Moreover, an analog correction technique has been developed to linearize a low-cost free-running UWB Voltage Controlled Oscillator (VCO) and to enable operating frequency selection. A functional demonstrator has been designed and associated measurements are proposed.
