Description: 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.
