提出了用联合变换相关器(JTC)来实现证据理论概率分配函数正交和的光学计算,在理论上对于如何用联合变像相关器实现证据理论分配函数正交和作了详细的讨论,并作了相应的仿真测试,结果显示该方法是可行的。与John Caulfield提出的用声光器件矢量外积实现的正交和计算相比,在该结构中由于采用二进制编码的数值计算,因此其计算精度得到了提高,同时对联合变换相关器输入端二进制编码的数值空间位置的适当调整可以直接得到所需要的证据理论正交和矢量,在处理步骤上得到了简化。 In this paper, the optical computation of quadrature sums of probability theory of evidence theory is proposed by Joint Transform Correlator (JTC), and the theorem of how to orthogonalize the evidence theory distribution function in theory is discussed in detail. The corresponding simulation test results show that this method is feasible. Compared with the orthogonality calculated by John Caulfield using the vector outer product of acoustooptic devices, the computational accuracy is improved in this structure due to the numerical computation using binary coding. In the meantime, the joint transformation of the correlator input binary The proper adjustment of the numerical space position of the code can directly obtain the orthogonality and vector of the required evidence theory and is simplified in the processing steps.
