Modified Physical Optics Approximation for RCS Calculation of Electrically Large Objects with Coated Dielectric

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...

FAST FAR FIELD APPROXIMATION FOR CALCULATING THE RCS OF LARGE OBJECTS y

A fast far eld approximation (FAFFA) is developed to estimate RCS of conducting scatterers. This method accounts for the interaction between subscatterers in two ways depending on the electrical distance between the subscatterers. For subscatterers separated by large electrical distance, their interactions are computed in three stages: (1) Aggregation, which computes the total eld at a group ce...

implementation of rcs software calculator using physical optics theorem (rcspo)

radar cross section (rcs) calculation is an important issue of objects stealth and identification. it is necessary to design the rcs software because of the high cost of rcs measurements in practice. in this paper, designing of efficient software using physical optics theorem for radar cross section calculation of the complex perfect electric conductors or complex dielectric objects for high fr...

Physical optics modeling of 2D dielectric lenses.

We propose an advanced physical optics formulation for the accurate modeling of dielectric lenses used in quasi-optical systems of millimeter, submillimeter, and infrared wave applications. For comparison, we obtain an exact full-wave solution of a two-dimensional lens problem and use it as a benchmark for testing and validation of asymptotic models being considered.
