Late time response analysis for the discrimination of multiple simulated objects in concealed threat detection

This paper investigates the use of Late Time Response (LTR) analysis for detecting multiple simulated objects using via Finite Element Analysis (FEA) in concealed object detection. The LTR results from a pair of simulated targets are presented individually and present within the same simulation. The simulation used a plane wave to represent the Ultra Wide-Band (UWB) signal from a Vector Network Analyser (VNA). The simulated targets are suspended in air and the perimeter of the environment is a perfectly matched layer. To allow for the de-convolution of the signal and the removal of background clutter post processing has been applied.
