基于协商对策的多平台目标跟踪冲突消解

以利用多平台对空中多机动目标跟踪为背景,针对各平台执行能力与跟踪精度不同所导致的任务分配与平台资源利用之间存在冲突的情况,研究了基于协商对策的多平台目标跟踪冲突消解方法。以提高机动目标跟踪精度为原则,在避免重复跟踪和目标遗漏的同时充分利用平台资源,通过比较各平台对不同目标的跟踪精度,根据具体态势优先或按顺序分配任务。基于Visual C++6.0对多平台多机动目标跟踪中采用协商对策实现冲突消解的方法进行了仿真,通过与随机任务分配时的跟踪精度比较,验证了该方法的有效性。     

Reconstruction resolution enhancement of EPISM based holographic stereogram with hogel spatial multiplexing

We investigate how the splicing mode of a holographic element (hogel) affects the reconstruction of a 3D scene to improve the reconstruction resolution of a holographic stereogram fabricated using the effective perspective image segmentation and mosaicking method (EPISM). First, the effect of hogel spatial multiplexing on holographic recording and reconstruction is studied based on the mechanism of recording interference fringes in the holographic recording medium. Second, combined with the influence of multiple exposures on the hologram's diffraction efficiency, the diffraction efficiency of the holographic stereogram is analyzed in the spatial multiplexing mode. The holographic stereogram is then regarded as a special optical imaging system. The theory of spatial bandwidth product is adopted to describe the comprehensive resolution of the holographic stereogram, which explains why hogel spatial multiplexing can significantly improve the reconstruction resolution of a holographic stereogram. Compared with the traditional printing method under the same parameters in optical experiments, hogel spatial multiplexing has a lower diffraction efficiency but a higher quality of reconstructed image, consistent with the theoretical analysis.
