摘要：
In this paper, an anti-jamming front-end is proposed for the satellite navigation receiver. Firstly, a seven-element receiving antenna array and an eight-channel (seven receiving channels and one calibration channel) radio frequency (RF) module are devised. Then, the interference suppression module based on the linear constraint minimum variance (LCMV) criterion are designed and analyzed. By using the LCMV-PI algorithm, the spatial domain information of the signal can be used to effectively suppress the interference. In addition, considering that the channel inconsistency will adversely affect the interference suppression algorithm and subsequent signal acquisition and tracking, a channel equalization scheme is devised to correct the channel inconsistency.
