摘要

Considering the actual sea clutter, a fractal noise AM-FM model is proposed. Based on the observed data of the sea clutter of fuze, for the first time, the fractal characteristics of fuze including the fractal dimension and multi-fractal are investigated. Experimental results indicate that the sea clutter of fuze have the properties of fractal. Compared with radar oceanic backscattering, the sea clutter of fuze possesses higher fractal dimension and less range of dimension variety, which shows that the fractal theory can be applied to sea clutter of fuze. The wide sense power spectrum of sea clutter was analyzed, which is similar to the power spectrum of narrow-band GWN AM-FM. The SCF and the WSCF of the sea clutter of fuze are analyzed. Both theory analysis and the simulation present the sea clutter of fuze can be effectively restrained by the WSCF, which is useful to the signal processing involved of sea clutter.
