Modified Physical Optics Approximation for RCS Calculation of Electrically Large Objects with Coated Dielectric
The Radar Cross Section of a target plays an important role in the detection of targets by radars. This paper presents a new method to predict the bistatic and monostatic RCS of coated electrically large objects. The bodies can be covered by lossy electric and/or magnetic Radar Absorbing Materials (RAMs). These materials can be approximated by the Fresnel reflection coefficients. The pro...
متن کاملUniform Diffracted Fields from a Perfectly Conducting Cylindrical Reflector with Modified Theory of Physical Optics
The uniform diffracted fields are calculated on PEC cylindrical reflector by Modified Theory of Physical Optics (MTPO). It is aimed to convert the noncontinuous solution to a continuous solution by finding a uniform equation which does not contain any expression converging to 0 in the denominator part. Three axioms of MTPO theory are used to construct the integral equations for the perfectly el...

متن کاملNovel Decomposition of the Physical Optics Surface Integral into the Geometrical Optics and Diffraction Contributions in Terms of the Modified Edge Representation Theory
The Physical Optic (PO) surface integral has been expressed in its basic components by the unique Modified Edge Representation (MER) currents line integration definition. The Scatterer Geometrical Optics (SGO) component field is associated with the Stationary Phase Point (SPP) bellowing to the illuminated region of the scatterer and the diffracted field component with its illuminated boundary. ...
متن کاملEfficient restoration of space-variant blurs from physical optics by sectioning with modified Wiener filtering
Digital images blurred by space-variant point-spread functions of uncorrected physical optics may be efficiently restored using Wiener filtering on overlapping subimage frames. Frame size must be tailored to accommodate the displacement-dependent spreading and shifting of physical pointspread functions at large field angles to prevent circular convolution edge effects from corrupting the frame’...
