Abstract :
The high frequency backscattering by rotating skew-plated metal blades was investigated experimentally. Radar cross section (RCS) was measured in an anechoic chamber. The RCS spectra, relating to Doppler effect, were got by fast Fourier transform (FFT) from time-domain signature. The main characteristics are the periodic fluctuating of time-domain RCS and the asymmetry of RCS spectrum. The results agree well with the computational analysis of past literature.
