Abstract:

The objectives of this study were to verify and validate the Simulated Radar Image SRIM Code Version 4.0 monostatic radar cross section RCS predictions. SRIM, uses the theory of Physical Optics PO to predict backscatter for a user specified aspect angle. Target obscuration and multiple reflections are taken into account by sampling the target with ray tracing. The software verification and validation technique followed in this study entailed comparing the code predictions to closed from PO equations, other RCS prediction software packages, and measured data. The targets analyzed were a sphere, rectangular flat plate, circular flat plate, solid right circular cylinder, dihedral and trihedral corner reflectors, top hat, cone, prolate spheroid, and generic missile. SRIM RCS predictions are shown for each targets as a function of frequency, aspect angle, and ray density. Also presented is an automation technique that enables the user to run SRIM sequentially over a range of azimuth angles. The FORTRAN code written by the author for the PO equations is also provided.
