| 摘 要： | 首次利用实测的引信海洋回波数据，分析其分形特性。从统计特性、自相似性、无标度区间分数维、多重分形特性等方面进行了研究，数据仿真表明引信的海杂波存在分形特性，和雷达杂波相比：前者的分维值明显高于后者；前者的分维值弥散区间略小于后者；通过IFS对杂波进行逼近，逼近的信噪比前者高于后者。从而表明，引信海杂波的分形程度较雷达杂波更好，更适合使用分形理论建模。这一结论对引信海杂波的分形建模、抑制海杂波干扰以及分形背景下引信对抗研究具有重要意义。

| Abstract: | Based on the observed data of the oceanic backscattering of fuse(OBF), for the first time,the fractal characteristics of fuze including statistical characteristic, self-similarity, scale-invariant fractal dimension and multi-fractal were investigated. Experimental results indicate that the OBF have the properties of fractal. Compared with radar oceanic backscattering, the OBF posesses higher fractal dimension, less range of dimension variety, higher SNR of restruction, and the fractal theory can be applied to OBF. The conclusion is vital to the fractal models of clutter, restraining of the oceanic clutter and fuze anti-Jamming. |
