Several popular bistatic calibration techniques are investigated and comparisons made between the relative merits of the various techniques. The analysis addresses sensitivity to object alignment error, sensitivity to polarization impurity, and ease

Several popular metallic bistatic calibration objects are investigated, including a sphere, long and short cylinders, dihedral, trihedral, circular disk and wire mesh. Comparisons are made between the advantages and disadvantages of various objects f

In this paper, we summarize the results of our efforts in developing a scalable distributed memory fast electromagnetic integral equation solver. The massively parallel scattering code, called LSSP, is based on a Galerkin discretization of the combin

A new antenna is proposed based on a structure first constructed by Menzel (1979) that utilizes the leaky wave phenomena of the first higher order mode. This work seeks to determine the effect on performance of the antenna due to varying geometries.

Using a parallel implementation of the multilevel fast multipole algorithm (MLFMA) called LSSP, large-scale scattering problems can be solved. However, as the problem sizes in terms of number of unknowns are increased, the memory requirements increas

We have reviewed the role of numerical noise (round off error) in different parts of computations. It is seen that product error is insignificant. Subtraction error can play a significant role when a system is ill conditioned or involves subtracting

Many people that use computational electromagnetics to produce data are interested in two factors: speed and accuracy. To appreciate the tradeoff, it is imperative that data creation be well understood. The speed and accuracy tradeoff produces error

Traditionally radar cross section has been defined as a far-field parameter. This paper presents a first order methodology for modeling target scattering (equivalent target RCS) as a function of range. Developments in 3-D scattering center extraction
