In this work, a wideband airborne reflector-based ground penetrating radar (GPR) is designed and proposed.The proposed GPR consists of 15 discrete panels, each panel supported by a single multi-rotor bar drain board unmanned aerial vehicle (UAV).A lightweight, wideband Vivaldi antenna was developed as the feed structure.The antenna operates within the frequency range of 100–500 MHz and has a bandwidth of 387 MHz.

The proposed antenna will possess a penetration depth of 2 m.Different panel configurations are studied and it is found that 15 discrete panels each with a dimension of 30 cm by 4 m and separated by 30 cm acts as a reflector antenna here with a high gain of 14.25 dBi.
