| 摘 要： | 针对传统扫描体制雷达(机扫雷达)无法分辨半功率波束宽度内存在多目标的问题,基于阵列信号处理的思想,应用加权子空间拟合(WSF)方法实现了机扫雷达超分辨估计.首先分析了机扫雷达幅度调制的导向矢量模型,然后推导了基于此导向矢量的WSF DOA估计方法.仿真结果表明,该方法具有较高的估计精度.

| Abstract: | It is difficult for a traditional mechanical scanning radar to distinguish multiple targets present in the mainlobe of the rotating antenna,thus we propose a method based on the idea of array signal processing.The Weighted Subspace Fitting(WSF) algorithm is used to implement super-resolution estimation of the scanning antenna.The steering vector model for amplitude modulation of scanning antenna is analyzed,and then WSF-DOA estimation method based on this steering vector is deduced.Simulation results demons... |
