A SOURCE DISTRIBUTION TECHNIQUE FOR THE SOLUTION OF GENERAL ELECTROMAGNETIC SCATTERING PROBLEMS. PHASE I REPORT
Abstract
The Source Distribution Technique ('SDT') embodies a comparatively simple and unrestricted computational method applicable to the complex problem of scattering from arbitrarily shaped geometries. The procedure exhibits a greater degree of flexibility and accuracy than present day approximation techniques. It is a numerical procedure for determination of the radar cross section for complex targets, based on an integral equation approach. It can be employed to determine the electromagnetic scattering from arbitrarily shaped two-and-threedimensional geometries in the difficult resonant frequency ranges in which classical solutions are not available. Combined with the Norair Physical Optics procedure the 'SDT' can be employed to determine the electromagnetic scattering of a variety of shapes, including large scattering objects; i.e. > 2 lambda. Verification of the technique was performed on the Norair radar reflectivity range. An image-plane was utilized to measure the current distribution and scattered fields. A brief outline of the basic procedure is described together with a few examples to demonstrate its validity.
