摘要: 针对固定单站无源定位必须实现快速定位跟踪的要求,提出一种基于空频域信息的定位方法。对该方法的定位误差进行分析,得到影响该方法定位误差的各因素,以及这些因素对定位误差的影响程度。仿真实验结果表明,该方法受角速度测量误差影响最大,受多普勒频率测量误差和运动辐射源的速度影响较大,受频率测量误差影响较小。

Abstract: To satisfy the requirement of high location speed, this paper presents a method based on the observed information of spatial-frequency domain by fixed single-observer. Location error analysis of this method is touched. The factors influencing the location error and the degree of influence are exploited in virtue of Geometric Dilution of Precision(GDOP) graph. Simulation experimental results show that this method is sensitive to angle velocity measuring error, and is evidently affected by the measuring error of Doppler frequency rate-of-change and the velocity of moving emitter. At the same time, the location error of the method is less affected by frequency measuring error.

Key words: spatial-frequency domain information, passive location, fixed single-observer, angle changing rate, Doppler frequency changing rate, location error
