存在阵元位置误差时的信号DOA估计，阵列误差，有源校正-When there is a sensor position errors DOA Estimation array error, active correction

Awareness of the physical location for each node is required by many wireless sensor network applications. The discovery of the position can be realized utilizing range measurements including received signal strength, time of arrival, time di

The Receiver Autonomous Integrity Monitoring (RAIM) is used to improve positioning system safety. This paper proposes a new RAIM approach to detect and exclude multifaults of GNSS measurements before position estimation. The new approach uses t
