•POFACETS is a RCS tool developed by Dr. Jenn of the ECE Dept. of NPS.
•It is based on the Physical Optics Method.
•Ship Parameters used by POFACETS were generated with RHINO software.

RCS Results using a PEC material model at a frequency of 0.3 GHz
Physical Optics Method
of RCS Estimation
Our second method of RCS estimation used POFACETS software to verify the empirical results and to determine the RCS as a function of:
1.Ship Material
2.Target angle
3.Operating frequency of the enemy seeker.

POFACETS is RCS estimation software based on the physical optics method.
It was developed within the Naval Postgraduate School’s Electrical Engineering Department by Dr. David Jenn and thesis students.

The Combat Systems team used ship parameters from HM&E generated with RHINO software.

On the right are shown both the Linear and polar results vs. target angle for steel, and a seeker frequency of 0.3 GHz.

The two plots show a median RCS for TENTACLE of around 25 dBsm, with peaks at more than 50 dBsm on the beams.
