摘　　要：为解决GPS抗干扰问题,设计和实现了一个GPS自适应天线实验平台.它主要包括天线阵、多通道射频前端和数据采集系统3部分.通过该实验平台,可以在真实环境中验证各种自适应算法并进行算法的性能评估.最后利用最小功率法对实验平台进行了测试,结果表明该平台能够对GPS卫星信号和干扰信号进行高质量的数据采集,以提供实采数据供各种抗干扰算法的后续处理.An adaptive antenna experimental platform for GPS is designed and implemented, and it is intended for use in GPS anti-jamming research. The experimental platform consists of an antenna array, multichannel RF front end, and a data collection system. Through the experimental platform, a variety of adaptive algorithms can be verified and thus the performance evaluation of adaptive algorithms can be made in real environment. The power inversion algorithm has been used on the experimental platform, and the results obtained demonstrate that the hardware platform allows collection of high-quality signal-plus-jamming data records for subsequent playback through a variety of anti-jamming algorithms.
