空频抗干扰对GNSS载波相位测量的影响
Effect of space-frequency adaptive processing on carrier phase measurements of Global Navigation Satellite Systems
摘要
Abstract
Adaptive antenna array technology is the most effective method for anti-interference of Global Navigation Satellite Systems(GNSS).However,this anti-interference processing generates carrier phase measurement bias related to the direction of signal incidence,which limits the effective application in high-precision measurement.In order to reduce the bias of anti-interference processing,an analysis method of introducing measurement bias is proposed,a corresponding model is established,and a software receiver is built for simulation experiments.The results show that without adding additional constraints,adopting the space frequency minimum variance distortionless response algorithm to achieve a space frequency anti-interference processor would not introduce carrier phase measurement bias,making it very suitable for applications in fields with strict requirements on anti-interference performance and measurement accuracy.关键词
