Reflector Cross Section Test Results
| The
following are renderings of actual Radar Cross Section (RCS)
patterns taken of the Tri-Lens and Mini Tri-Lens along with
four of the most popular reflectors on the US market today.
(Davis Echomaster, Mobri S-2, Mobri S-4, and the Firdell Blipper)
The testing was conducted by the US manufacturer of the TriLens,
Rozendal Associates, Inc. in one of their anechoic chambers
on November 17, 1999. The frequency was 9.5 GHz. The polarization
was horizontal. This is the frequency and polarization that
is a marine standard. The pattern of each reflector is approximately
120 degrees wide. |

You
can assume the reflected pattern would look very similar for 360
degrees. The area of 1 square metre and 2 square metres is marked
on each pattern. The Tri-Lens and Mini Tri-Lens have a far superior
signature than that of any other pattern. The other patterns have
some peaks but many areas fall below 1 square metre and even go
below 1/10th of a square metre. This would be very difficult for
a ship's radar to see. Ideally the more pattern above the 1 or 2
metre line, the better the performance of the reflector.
