The growing professional interest in ground-penetrating radar (GPR) is driving the need to formulate methods for characterizing the performance capabilities of GPR systems. Because a number of different factors, such as antenna ringing, noise, radio frequency interference and receiver dynamic range, contribute to limit a GPR's capability, no single performance measure gives an adequate system characterization. Instead capability can best be described by indicating the boundary of marginal performance for the various parameters that affect performance in the form a waveform-range performance diagram. The various limiting processes are used to define the performance boundaries. Within the performance boundary the radar has a capability, and outside the boundary the radar has no capability. Performance measures such as system performance, loop gain, and system dynamic range are interpreted using the waveform-range performance diagram. |
