系留载平台可以实现高远程预警与持续悬停于空中,适用于空基组网实现无源定位。以系留载平台为对象,对比系留载平台与陆基和空基运动平台,归结其特有的优势与军事价值,对系留载组网无源定位进行分析。依托系留载组网,首先构建典型的三系留载体系结构,再采用盲信号处理方式从复杂电磁环境分选识别出威胁信号;最后,采用“定位精度的几何稀释”对误差进行深入分析,构建数学模型,提出最佳定位点的选取并进行仿真验证。该文为后续的日后无源定位的布站应用提供借鉴。
The mooring platform can achieve high long-range warning and continuous hovering in the sky, which is suitable for space-based networking for passive location. Taking the mooring platform as an object, the mooring platform and ground-based and space-based mover platform are contrasted to analyze their unique advantages and military values. Relying on mooring network, we build a typical three-line system and use blind signal processing method to identify the threat signal from complex electromagnetic environment. Finally, we use “geometric dilution of positioning accuracy” In-depth analysis, construction of mathematical models, the selection of the best positioning points and simulation. This paper provides reference for the subsequent application of passive positioning station.
