基于经验模板匹配算法的无线电引信探控模型

Detection and Control Model of Radio Fuze Based on Experience Template Matching Algorithmic

针对目前无线电近炸引信仿真中有限元分析法计算周期较长且无法直接给出引信终端信号的不足,以物理光学法、绕射理论为理论基础,结合交会条件解析引信探测状况,以平面、尖劈、孔径、台阶等单元散射模型为模版进行快速匹配,得到引信终点弹道段探测与控制功能工程化快速计算模型。通过试验数据的对比表明:在计算效率得到保证的同时,计算结果与实测数据具有较好的一致性。

The present radio fuze simulation using elements analytical method has the disadvantages of long calculating period and no direct output of fuze terminal signal.On the basis of physical optics theory and diffraction theory,combining with encountering condition analysis of fuze detection,some single scattering models such as plate,hack,aperture and step were taken as fast matching templates,a fast calculation model of fuze terminal trajectory detection and control was founded in this paper.On the premise of an ideal calculating efficiency,the simulation results indicated that contrastive testing data matched with measured data well.
