基于空频域信息的固定单站无源定位技术研究
Research on Fixed Single-observer Passive Location Technology Based on Spatial-frequency Domain Information
摘要
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.关键词
