摘要

针对随机脉冲推力控制下的空间机动目标跟踪问题,提出一种基于状态信息和轨道信息的实时跟踪算法。该算法通过基于机动推力αβ动力学模型和改进当前统计模型的并行计算滤波器,完成空间非合作目标高精度实时跟踪。同时,利用直观的轨道信息,完成机动检测,采取重置滤波参数的方式获得更快的收敛速度和稳健性。仿真实验表明该算法可有效检测机动,实现了对非合作目标机动目标的轨道确定,具有一定的工程实用性。

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
