How to Hide an Airplane: A Study of Radar Cross Section, Year 2

Overview

Objectives/Goals To determine why certain shapes are used in aircraft and which radar systems perform the best in detecting these aircraft. Methods/Materials Black box, 2 LED Lights, LUX meter, shapes and 3 aircraft all white Results Sphere shape provided most light reduction compared to the control, wedge provided the least. Wedge shape provided most reduction when compared to corresponding 2-D cross section, cylinder performed the worst. F-22 had the lowest RCS reading on monostatic test, A-10 had the highest. A-10 had lowest RCS reading on bistatic/multistatic test, F-22 had the worst. Conclusions/Discussion In the 1st test the sphere performed the best due to its rounded shape design reflecting the light all in random direction. In the 2nd test the wedge performed the best by reflecting the light in a 2 uniform directions. The F-22 performed the best in the monostatic radar test due to its curved stealthy design. The A-10 performed the best in the bistatic/mulistatic test due to its small compact design.
