Overview of Observability of Bearings-only Target Motion Analysis
摘要
Abstract
Bearings-Only Target Motion Analysis (BOTMA) is an efficient method for passive localization and tracking due to the superiority of which uses only bearing measurements to estimate parameters of target motion. The researches of bearings-only systems concentrate on three aspects:observability conditions,target tracking and estimation strategies and optimal observer maneuver trajectories. The observability problem is the key issue that is to be handled firstly because the corresponding observability conditions are the basis and precondition of follow-up researches of target localization and tracking. First,the basic concept of observability in bearings-only system is introduced. Then from the research methodology perspective,the existing BOTMA observability research results, including geometric methods,linear and nonlinear system based methods and numerical methods,etc., are summarized and reviewed. Finally,several new opinions on future researches in this area are presented.关键词
