Radar cross-section is a key element of low-observability. In order to reduce the cross-section of a particular platform, it may be necessary to determine the induced source distribution on the platform which produces the scattered electromagnetic radiation. Determining the distribution may be possible using a probe to measure fields on or near the outer surface of the object. However, the act of measuring may indeed influence the currents being measured. An alternate method is to back-propagate measurements made at distances beyond the realm of strong influence on the parameters of interest to construct visualizations of the local on-surface radiation contributions. This has been demonstrated for the case of cylindrical geometry. The theory is extended in this thesis to axisymmetric bodies for the special case of rotationally symmetric fields
