Abstract

The field of view of optical imaging systems is limited, making it difficult to meet the needs of continuous tracking of multiple targets in different orientations in a wide spatial domain, even in the 4 π spatial domain. Therefore, based on the two-dimensional tracking rotating platform, an unscented Kalman motion estimation algorithm based on target motion characteristics and an optimization algorithm for multi-objective switching tracking based on motion target matching, tracking convergence, and platform rotation ability have been proposed. The ultimate goal is to achieve continuous tracking of multiple spatial targets over a wide area. The development of a light and small space two-dimensional rotating platform tracking system is completed. The target detection coverage achieved is better than ± 180° in both pitch and azimuth directions. Continuous observation and tracking of better than 8 targets has been achieved through target motion estimation and switching tracking methods.
