    Abstract
  • Radar scattering characteristics of two stealth fighter models were tested and analyzed. The models were stealed with the following procedures: controlling the radiating directions and numbers of main scatter sources, increasing the occupation ratio, surface metalizing, leaning the intake lips in three directions, and designing the gaps of the aileron as rhombus. The main results and conclusions are as follows: RCS values of both models are less than 1 m2, meaning that the stealth characteristic in nose direction is of great importance to the design of modern fighter. It is of benefit to stealth to reduce the number of scattering directions. Incomplete dihedral reflector constructed with the leaned tailer and wing, fuselage or stabilizer is a strong scattering source.
