Abstract
A novel infrared mono-station passive location algorithm for a maneuvering target is presented based on infrared imaging, series images processing and three dimensional movement analysis. The algorithm results in the relative distance between the maneuvering target and the measurement station by using the measured information of infrared imaging target. It accurately reflects the actual situation of complex relative movement between the mobile target and the mobile measurement platform, effectively overcomes the bad influence of the gesture change in the target itself and the pseudo-gesture change in the target caused by the relative movement between the mobile measurement platform and the mobile target on ranging precision, objectively reflects the various actual states on the complex relative movement between the mobile measurement platform and the mobile target. It is applicable to such relative motion models between the maneuvering target and the maneuvering measurement station as the invariable velocity, invariable acceleration and variable acceleration and so on with high location precision, small cubage and great mobility. The correctness and validity of the algorithm are illustrated by both the computer digital simulation and the semi-practicality visible light imaging simulation. Under the conditions of satisfying the measurement precision requirements on the image and angle parameters of the target, the relative error of measuring distance is not larger than 5%. At the same time, the algorithm is also suitable for visible light mono-station passive location.
