Abstract: Methods and systems are provided for characterizing an overhead line. A radar signal is propagated in a region that includes at least a portion of the overhead line and a reference object, which may, for example, be a ground surface, growth over a ground surface, or another overhead line. A reflected radar signal is received from the overhead line and the reference object. A determination is made of a geometric relationship between the overhead line and the reference object, such as by determining a minimal separation between the overhead line and the reference object.

Abstract: A radar source is configured on a vehicle, which may be an airborne vehicle such as a helicopter. An arrangement of at least one computer system is provided in communication with the radar source and configured to accept instructions from an operator and to operate the radar source. As the vehicle moves in the vicinity of a subterranean volume along a navigation path, a radar signal is propagated with the radar source into the subterranean volume. A reflected radar signal from a subterranean object within the subterranean volume is received. Physical characteristics of the subterranean object are ascertained from the reflected radar signal.

Abstract: A method and system for identifying an anomaly in an electrically insulative component of a structure, such as an insulator on a utility or telecommunications pole, are provided. Locations for the structure and electrically insulative component are identified. A radar signal is propagated towards the electrically insulative component with a radar antenna while the radar antenna is motion along a navigation path in the vicinity of the structure. A reflected radar signal is received from the electrically insulative component, from which a determination is made whether the electrically insulative component contains the anomaly.

Abstract: A method and system for analyzing a wooden structure, such as a utility or telecommunications pole, are provided. A location for the wooden structure is identified. A first radar signal is propagated towards the wooden structure with a radar antenna while the radar antenna is motion along a navigation path in the vicinity of the wooden structure. A reflected radar signal is received from the wooden structure, from which a determination is made whether the wooden structure contains a structural anomaly.
