RAT SCAT Evaluation of Commercially Available Radar Absorbing Materials

Abstract

This report summarizes performance evaluation tests on a variety of commercially available thin flexible sheet type radar absorber materials, including both resonant and non-resonant types. A corner reflector test technique was used which allowed test and evaluation of the absorber at both normal incidence and grazing angles out to ninety (90) degrees. Fourteen types of RAM were tested at frequencies near 11, 13, 17 and 35 GHz. The higher frequency data and off-normal incidence data in this report are often unavailable in RAM manufacturers literature. RAM types tested include: FGM-40, ANW-73, ANP-74XP, AN-73, AN-72, AN-75, ANP-73, NRL-2764B, SF-14, GRAM-52 and NR-95. This report provides reproductions of the data runs taken and 5 degree median plots of each run. The measurement configurations and parameters for each cut are identified on each pattern with an overall summary chart included in the main body of the report.
