Radio frequency interference (RFI) poses a severe problem for conventional GNSS receivers. Even low powered RFI can block the reception of satellite signals and prevent a position determination. Antenna array systems have been proven suitable to counteract RFI by incorporating spatial processing techniques. The large size of uniform rectangular arrays (URA) with half‐wave antenna spacing impedes an installation in cars intended for the consumer mass market, where a hidden installation is a strict requirement by industry and customers.

使用空间分布子阵列的新阵列概念可在汽车应用中实现毫不含糊的GNSS干扰缓解

射频干扰（RFI）对常规GNSS接收器造成了严重的问题。甚至低功率的RFI也会阻塞卫星信号的接收并阻止位置确定。事实证明，通过结合空间处理技术，天线阵列系统适合抵消RFI。具有半波天线间隔的统一矩形阵列（URA）的大尺寸妨碍了在面向大众市场的汽车中的安装，在该市场中，隐藏安装是行业和客户的严格要求。
