| 摘 要： | 本文在空间域的带限信号外推的基础上,提出了一种新的提高阵处理分辨力的方法。为了克服阵元间距为半个载波波长时空间域带限信号外推的困难,文中利用了一种预处理方法。模拟结果表明新方法比现有方法具有更高的分辨力。 |

| Abstract: | A new array processing algorithm based on a spatial extrapolation is presented to enhance the resolution. To overcome the difficulty of a spatial extrapolation when a sensor spacing is halfwavelength, a preprocessing scheme is utilized. The proposed algorithm can give much better results than the existing array processing methods. Simulation results are given. |
| Keywords: | Signal processing Array processing Radar signal processing Band-limited signal extrapolation. |
