| 摘 要： | 相控阵雷达系统中多个A/D通道之间幅度、相位特性存在的不可避免的差异,降低了后续雷达数字信号处理使用数据源的精确度,从而影响了雷达系统的分辨率。针对这一问题,作者提出了一种自适应修正多A/D通道之间幅相不一致性的方法。实验证明该方法实现简单、修正结果较好、有较强的工程应用价值。

| Abstract: | In phased array radar system,multiple A/D channels have different amplitude and phase characteristics unavoidably.This difference reduces source data accuracy in radar digital signal processing and has seriously affecting on phased radar resolution.In order to solve this problem,the author proposes an adaptive correction method which can revise this difference among different A/D channels.Experiment shows that this method is simple to realization,has excellent correction results and Engineering applications... |
