摘要: Array antenna beam forming has high potential to improve the performance of global navigation satellite system (GNSS) in urban areas. However, widespread application array antennas for GNSS multipath mitigation is restricted by many factors, such as complexity system, computation load and conflicts between required performance, cost budget limited room placement. The scope this work triplicate. (1) pre-correlation structure first suggested decrease complexity. (2) With structure, equivalence adaptive quiescent revealed. Therefore, computational greatly decreased. (3) A theoretical model established link benefits with improvement terms pseudorange quality. can be used industry balance aforementioned restrictions. Numerical results different settings are given, a 2 × rectangle element spacing cost-effective choice positioning applications canyon
