摘要
阵列信号处理是当前信号处理的热门方向,为信号处理带来极大的方便,阵列信号处理中的各通道不一致问题将会给阵列信号处理带来影响,很多文献中介绍过关于自适应幅相误差校正的理论及方法 ,但实现起来都比较耗费资源和时间,且效果有待实践验证。提出一种工程上可实现且计算量较小的通道校正方法-查表法。通过仿真,结果表明此方法可以对特定来向的有用信号进行较为准确的校正。
Array signal processing is a promising aspect of digital signal processing,it brings much convenience to digital signal processing. But the difference between each channel is a big problem in Array signal processing, which must be eliminated some times. We can find a lot of calibration methods of the amplitude and phase error among RF channels in many papers, but most of them need too much computation and time, and the effect is unknown. A new calibration method-look up table method is put forward, which are very easy to realize. The MATLAB simulation result reflect its serviceability.
