RADAR CROSS SECTION ESTIMATION AND ANALYSIS: HIGH FREQUENCY- BASED METHODS

Radar Cross Section Estimation and Analysis: High Frequency- based Methods

The RCS estimation and analysis of different canonical and hybrid shapes has been carried out with the help of surface modeling, ray tracing, and methods like physical optics (PO), physical theory of diffraction (PTD), geometrical optics (GO), geometrical theory of diffraction (GTD), uniform theory of diffraction (UTD), and method of equivalent currents. The RCS estimation involves analytical formulation, application of appropriate boundary conditions, software code development, simulations and analysis. The structures can be conducting or coated conducting ones.
