Summary form only given. The desire to anticipate, find, fix, track, target, engage, and assess, anything, anytime, anywhere (A2F2TE4A) by the US Air Force will require changes to how we modify, build, and deploy monostatic and multistatic radar systems. The multistatic ambiguity function has been proposed as a tool for analyzing and designing multistatic radar systems. It was demonstrated through...
When electromagnetic fields strike sharp surface discontinuities, such as edges and corners, they create a diffraction phenomenon. In high-frequency methods, the field generated when a wave impinges upon a PEC wedge can be accounted by using geometrical optics (GO), based more on Snellpsilas law of reflection, and diffraction, based on Fermatpsilas principle for diffraction [1]. The diffraction phenomenon...
EFIE (electric field integral equation) suffers from internal resonance, and the remedy is to use MFIE (magnetic field integral equation) to come up with a CFIE (combined field integral equation) to remove the internal resonance problem. However, MFIE is fundamentally a very different integral equation from EFIE. Many questions have been raised about the differences.
In this paper a technique is presented on how to enhance the received signals in a near field multi-input multi-output (MIMO) environment where beam forming is not possible. This is done through the use of adaptivity on transmit. Polarization diversity can also be implemented. This technique is based on the principle of reciprocity, is independent of the material medium in which it is transmitting,...
In a previous paper we compared the radiation Q for practical electrically small antennas as a function of aspect ratio to various minimum Q formulas, including the minimum Q for the first order mode of spheroidal shapes. One conclusion was that the lowest order spheroidal mode does not give the minimum Q because at high aspect ratios certain practical antennas were shown to have lower radiation Q...
