Radar systems, based on bistatic radar concept attracted a substantial attention in the recent years. Passive coherent location systems using “transmitters of opportunity” like radio or TV broadcasters, GSM base stations, satellite communicat

对于城市环境中的高精度单频 GNSS 接收机而言，若考虑误差预报处理已抵消电离层误差，则地面传播环境所导致的多径效应将成为系统误差的主要因素。基于现有蜂窝通信的高分辨率信道估计结果，针对电波传播的幅度、相位、多普勒等特征提取信道响应函数，在极小误差范围内提供至 L 波段信号的线性特征映射-For multipath effects in urban environments with high accuracy single-frequency GNSS receiver, the foreca

Interoperability and compatibility is the main goal for current GNSS systems. A concept of Global Navigation Satellite System (GNSS) is to use all navigation system together to provide better capabilities compared with those that would be ach
