Use of radar for illegal connections prospecting in buried or embedded cables

The purpose of this paper is to present a proposal to locate illegal connections underground using a technique to inject radar signals and collect their measurements. In special analyses, the reflection on the ground in the case of electrical conductors forms a hyperbola. Utilizing the radius of curvature variations of the hyperbola, the texture and tonal intensity of colors, it is possible to identify and differentiate between water pipes, gas pipes, tree roots, and others materials grounded. A testing area was built in a substation, where types of cables, containing branches, simulating clandestine links were buried in ditches. To support the analysis, a computational tool was developed to identify objects through statistical analysis of the radar grams, pixels, colors, and intensity.
