Radar cross section (RCS) data are measured from a realistic aircraft jet engine structure with rotating parts, and the characteristics are analyzed. The model has an inlet with dimensions of 0.866 m x 0.866 m x 0.703 m, 35 degree skewed three stage rotor blades attached to the rotating shaft with a motor, and the number of blades are 17, 29, and 41. The experimental results show that the jet engine modulation (JEM) patterns are very complicated and can be used to extract meaningful distinct features.
