The present research study proposes a technique for generating an impulse-radio ultra-wideband (IR-UWB) pulse through the utilization of a field programmable gate array (FPGA) board. Through the wall radar imaging (TWRI) now plays a crucial role in detecting humans during earthquakes, terrorist attacks, by rescuing people and patients whose lives are in danger. Advanced FPGA boards like EDGE Artix-7, ZYNQ ZC 706 were incorporated into the experiment for rapid data acquisition, transmission, and generation of signals and applied to the target. The FPGA scheme comprises three primary elements such as digital clock generation, four delay lines, and an edge combiner (XOR logic) that yields high-frequency ultra-wideband (UWB) pulses in the gigahertz (GHz) range. The use of an FPGA approach with four different architectures with buffers, NAND, NOR and MUXs logics were applied to generate an IR-UWB pulse with high range bandwidth applicable for obstacle detection, tracking and ranging.
