A radar sensor design and prototype for through-the-wall imaging radar applications

In this work, we present the complete design and prototype processes for a radar sensor that can be used for Through-The-Wall Imaging Radar applications. The simulation and optimization of the antenna element were done using CST Electromagnetic simulator software. The full array that was composed of 8-Vivaldi antenna elements aere also simulated and optimized using CST. The radar sensor was configured by the 8-element Vivaldi array, RF transceiver, RF switch, microcontroller and computer set-up. The final production of the radar sensor was presented and the integration steps of the sub units were shared. The good agreement between the simulated and the measured results for the antenna parameters demonstrate the success of the design and prototyping process.
