用于目标跟踪的传统成像系统瞬时视场小、且为实现大范围覆盖需要对目标空域进行扫描，为了能解决宽视场覆盖和高分辨率的问题，提出一种新的基于空间多路成像技术的可直接判定宽视场中目标位置的目标跟踪方案。该方案利用多镜头阵列组合设计一种多光路、共焦平面、宽视场凝视成像系统结构，这种结构要求分割的各子视场之间有特定的重叠编码关系，以便同时成像之后解算目标位置。针对一维镜头阵列组合的情况，研究分析了镜头阵列的空间位置关系、各子视场编解码原理以及在目标跟踪技术中的应用，并在此情况下对简单目标跟踪算法做了研究和仿真。结果表明该方法能很好地实现在大视场中对目标的跟踪。

The two disadvantages were known in traditional imaging system for target tracking, which were small instantaneous field of view and the need to scan the target airspace for the realization of the large coverage. In order to solve the problem of the wide field of view coverage and high resolution, a new method for target tracking was proposed based on spatial- multiplexing imaging technology, in which the target position was determined directly in the wide field of view. And a starring imaging system structure with an optically multiplexed path, a common focal plane and a wide field of view was formed by the use of multi- lens array, which requires a specific overlapping and encoding relationship between each of the divided sub- field of view to decode the target location after imaging simultaneously. Focused on the one- dimensional lens array, the spatial relationship of the lens array, encoding and decoding principle of the field of view and its employment in target tracking technology were all analyzed. In addition the target decoding algorithm was studied and simulated, the simulation results demonstrate that this method can solve the target tracking problem of a wide field of view effectively.
