Optically multiplexed imaging technique for target tracking

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.
