Abstract

A new method was presented based on input and orbit information for space non-cooperative target tracking during random thrust maneuvering process. It is composed by two filters in parallel, the main one is constructed by dynamic model and the auxiliary one is constructed by improved current statistic model. The two filters run for estimating real-time and precise filtering results. Meanwhile, maneuver detection is done based on the orbit information. If the maneuver is detected, changing filter parameters are introduced to obtain faster and smooth tracking results. Simulations show that the result of the new algorithm is much superior to traditional ones. The algorithm has certain engineering practicability.

Key words： input and orbit information; a-β dynamic model; improved current statistic model
