GPS 矢量跟踪建模与抗干扰性能分析
Modeling and Anti-Interference Performance Analysis for GPS Vector Tracking
摘要
Abstract
The anti-interference performance of GPS vector tracking loop is discussed deeply .The systematic models and bandwidth models of vector delay lock loop and vector frequency lock loop are es -tablished , and based on the analysis for noise bandwidth of vector tracking loop , it is illustrated that vec-tor tracking loop is capable of adaptively adjusting the noise bandwidth to adapt to the interference envi -ronments of different intensity .The interference-to-signal ratio is computed with the measurement errors within vector tracking loop to determine the anti-interference performance in complex environments .Com-pared with scalar tracking loop , GPS vector tracking loop has stronger anti-interference ability .关键词
