基于协变光谱随机场理论的激光引信背景模型

针对目前激光引信仿真中传统地海杂波算法求解困难、计算效率低且适用范围小的问题,对传统算法进行改进,提出基于协变光谱随机场理论的激光引信背景模型。该模型首先找到具有真实背景场统计特征的协变函数,其次结合光谱理论将随机场亮度分布求解转化为随机频率、功率谱及概率密度求解,最后融合上述理论得到背景模型。经实际测试验模表明:模型精度误差小于20%,可用于激光引信背景仿真。

Background Model of Laser Fuze Based on Covariant-spectral Random Field Theory

Aiming at the problems of arithmetic solving difficulty,low computational efficiency and small subject range on traditional sea clutter algorithm for laser fuze simulation,the model of laser fuze background based on correlative-spectral random fields theory was proposed.At first,the model found the covariant function with the statistical characteristics of the real background field;then combined with the spectral theory,it could translate the solving of random field brightness distribution into the solving of random frequency,power spectrum and probability density;At last,with the combination of the theories above,the model was obtained.Practical testing indicated that the accuracy error of the model was below 20%,it could be used in laser background simulation.
