摘要

本文主要研究空间预警系统利用星载红外传感器的视线测量估计弹道导弹自由飞行段弹道的问题.针对目标运动的弱可观测性

提出了只约束位置的改进Gauss-Newton方法

解决了弹道的最大似然估计问题

并利用Monte Carlo仿真实验验证估计算法的有效性

且对估计误差进行了分析.

Abstract

Using line of sight (LOS) measurements from space-based infrared sensors

ballistic trajectory estimation problem of ballistic missile is studied in this paper.Taking into account poor target motion observability

an improved position constrained Gauss-Newton algorithm is proposed to solve maximum likelihood estimation problem of trajectory.Monte Carlo simulation verifies the efficiency of this algorithm.And

estimation error is analyzed.
