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. |
