Modulation effect analysis by rotating screw metal fans

摘要

In this paper, the backscatter field of the rotating screw metal fans are investigated based on PO/PTD (physical optics/physical theory of diffraction) and the method of equivalent currents (MEC), in conjunction with the quasi-stationary method. The time and frequency domain responses of the radar return signals are predicts. The modulation effects by the radar return signal of rotating screw metal fans is analysis. These results can be used in the target identification.
