Abstract:

An algorithm based on a constrained total least squares combining adaptive interactive multiple model (CTLS-AIMM) is developed for the tracking of near space vehicles. First, taking near space vehicle characteristics into consideration, an early-warning satellite system is used to detect the target, and a constrained total least squares algorithm (CTLS) is used to calculate the pseudo position information roughly, based on which an adaptive interactive multiple model (AIMM) algorithm is developed for the real-time tracking. In the AIMM algorithm, appropriate model-sets are selected according to the characteristics of a near space vehicle, to describe the target motion, and iterative least square is used to calculate the adaptive parameters. A hypothetical scenario is taken as a testing case, and computer simulations show the effectiveness of the methods.
