多波束天线通道幅相一致性校正及实现

A correction system of DBF antenna’s receiver based on LMS and its realization

本文针对多波束天线接收机的通道幅相一致性校正,提出了一种基于自适应算法的校正方法并在FPGA中实现了该方法。在满足系统要求的前提下,该方法不但实现起来相对容易,而且算法的精度和动态范围也有一定的保证。仿真和试验结果表明,该方法是可行的。

This paper discusses the channel-correct of the receiver used in DBF antenna and presents a method based on the adaptive algorithm. This method is realized in the Field Programmable Gate Array （FPGA）. On the premise of satisfying the requests of the system, it＇s comparatively easy to implement the method, and the precision and dynamic range of the algorithm can be ensured definitely. Finally, the simulation results show that this method is feasible.
