摘要

多传感器融合定位精度的定量分析是防空系统中的一个重要问题。根据主被动传感器融合定位的基本原理，通过CRB (cramer-rao boundary)方法建立了通用的GDOP (Geometric diffusion of Precision)计算模型。利用该模型系统分析了影响多传感器融合定位精度的主要因素，验证了该模型的可行性和合理性，对多传感器定位具有实用价值。

Analysis of Multi-sensor Fusion Localization Accuracy Based on GDOP

Quantitative analysis of multi-sensor fusion localization accuracy is an important issue in air-defense system. According to basic principle of fusion localization of active and passive sensor, a general GDOP (Geometric Dilution of Precision) calculation model was established through CRB (cramer-rao boundary) method. Using this model, main influence factors of multi-sensor fusion localization accuracy were analysed systematically, which verifies the feasibility and rationality of the model and has practical value for multi-sensors placement.
