It has been shown that the output from in-house ray-tracing simulation software provides a means by which the impulse radar response of a structural system can readily be simulated. Radar simulations were undertaken of re-bar targets in a tank. A 900 MHz commercial antenna was simulated. The simulations undertaken have shown the effects that target spacing and depth have on the radar signature shapes and the results compare well with real-case survey plots. Simulation data have been used to assess the output specification from a commercial antenna, with interesting findings. It is expected that simulation will allow the interpretation of actual surveys to be more readily understood, which will in turn allow a better engineering assessment to be made of a structure under investigation.
