Pagination or Media Count:
Static radar cross section RCS of a single-engine low-wing Piper PA-28-140 Cherokee Cherokee 140 was measured at 2700, 2800, and 2900 MHz S- Band over a range of aircraft attitudes of plus or minus 10 degrees pitch, 0 degrees to 45 degrees roll, and also at 1250, 1350, 5000, and 5400 MHz at 0 degrees roll, 0 degrees pitch. Median RCS in circular polarization and in linear polarization was independent of frequency. At S-Band the median RCS varied with roll angle most strongly in the two broadside directions. In those two directions the variation was greatest for linear polarization when the radar viewed the lower surface of the aircraft, and was greatest for circular polarization when the radar viewed the upper surface of the aircraft. Median RCS at S-Band was not affected by pitch angle.
