—A microgenetic algorithm has been applied to design a new ultrawideband thin-wire bow-tie antenna for ground-penetrating radar applications. The broadband performance of the antenna is achieved by resistive loading and by optimizing the number of wires and the angular distances between those wires. The radiation characteristics of the optimized antenna are(More)
In this paper we describe the discontinuous Galerkin time-domain method and apply it to the simulation of ground-penetrating radar (GPR) problems in 3D. The method is first validated with analytical solutions and we show its superior behaviour when compared to the classical finite-difference time-domain method, widely employed in GPR simulation. In the(More)
—This communication presents a prediction algorithm for the detection of features in GPR-based surveys. Based on signal processing and soft-computing techniques, the coupled use of principal-component analysis and neural networks enables a definition of an efficient method for analyzing GPR electromagnetic data. Results for detecting features of geological(More)
