Abstract :
In this paper, the backscatter field of rotating screw metal fans is 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 predicted. The modulation effects by the radar return signal of rotating screw metal fans are analysed. These results can be used in target identification.
