This communication presents an end-to-end model of continuous-wave ground penetrating radar using Matlab Simulink. This model includes the modelling of a radar system, soil environment with associated attenuation and reflection of the incident signal and the target and its positioning. For a chosen frequency of operation, isolation between the antennas, soil composition and target simulations are carried out by keeping the target at a different depth. The simulation results are validated by experimenting with a ground-penetrating radar prototype. For validation, experiments with two different sized targets kept at different depths in two types of soil have been conducted and compared with simulation results. This validation demonstrates that the proposed model closely approximates the physical design. The presented model demonstrates the potential for reducing the time and the number of design and development iterations for realizing a continuous wave ground-penetrating radar, physically.
