摘要

位置信息场定位法对强弱信息多目标进行定位时,存在对弱信息目标不能定位的问题。针对这个问题,提出了强弱信息多目标位置信息场定位算法,采用按目标位置信息场场强由强到弱的顺序逐级抽取的方法实现对多个目标的顺序定位。仿真结果表明,该方法可以有效实现对强弱信息共存多目标的定位,且定位性能受测向误差与目标间距的影响。

Abstract

The position information field location method can't locate target with weak information in the case of existing targets with strong information. According to this problem, a position information field location method for multi-target with different information power was proposed in this paper. The step by step extraction (SBSE) method was employed to locate each target in the order of targets' position information field power. Simulation results show that the proposed method can effectively locate coexistence targets with strong and weak information power, and the performance is affected by the DOA error and the distance among the targets.

Key words： position information field; strong and weak information; multi-target; step by step extraction
