双通道视频信息处理数据融合技术

Data fusion technique for video information processing of dual-channel

“飞鱼”类掠海反舰导弹已对水面大型舰艇的生存构成重大威胁,而近程反导舰炮武器系统是反“飞鱼”类掠海反舰导弹的最后防线。因此,实现成功拦截掠海反舰导弹,精确稳定地自动跟踪目标,是近程反导舰炮武器系统的关键技术之一。阐述了适合自动跟踪高速飞行掠海导弹的双通道视频处理器的构成。对工作原理、去噪预处理、图像分割、特征抽取、识别和位置检测等技术作了简要说明,并对核心部分——双通道视频信息的资源利用和数据融合处理作了较详细的论述。双通道并行处理数据融合技术在国内首次应用于××近程反导舰炮武器系统光电跟踪仪中,在海上定型试验中取得了很好的跟踪效果。

Wave-hopping anti-ship missiles such as “Exocet MM38”, etc. are serious threats to heavy surface vessels, and the ship-borne close-in weapons system is the“last chance” defense against the anti-ship missiles. Therefore, as for the interception of the wave-hopping anti-ship missiles, the accurate, stable and automatic target tracking is one of the key technologies for the system. The constitution of the dual-channel video processor, which is adapted to tracing the wavehopping high-speed missiles automatically, is presented in this paper. Some technologies of the processor, such as operation principle, noise suppression preprocessing, image segmentation, signature extraction, recognition and position detection, are briefly introduced. And the central part （the resource utilization and the data fusion processing of the dual-channel video information） is discussed in detail. The dual-channel parallel processing data fusion was applied firstly at home to the optoelectronic tracking instruments of shlp-borne close-in weapons systems, and a satisfactory tracking effect was achieved in the demonstration test on the sea.
