提取频谱稳定度差异探测舰船目标

Extaction Difference in Spectrum Stability for Ship Target Detection

寻找目标与环境的差异,探测目标的存在,同时降低对各类干扰的虚警,是水雷目标探测的首要任务。文章在归纳并分析舰船噪声与环境噪声的基础上,提出利用两者的频谱稳定度差异来探测舰船目标,并结合实测数据,进行了仿真,结果表明,该方法适应性强,智能化程度更高。

Extaction the difference between target and environment, improve the standard of detection,it is the principal task of mine passive acoustic target detection. Based on analysis of acoustic characteristics of ship＇s radiated noise and environment noise, this paper pres- ents extaction the difference in spectrum stability for ship target detection, the validity is verified by experimental data. This new method is more adaptable and intelligent.
