摘　　要：本文分析了超宽带(UWB)脉冲波形对圆盘形天线阵列的角度分辨率的影响,对UWB圆盘形定向天线阵列中的波形进行了优化。文中给出了具体的例子,得出了优化波形。优化波形比相应的Gaussian波形在角度分辨性能上得到了明显的提高。The relation between the average received power patterns and the pulse waveforms of disk arrays are analyzed, and the pulse waveforms are optimized to improve the angular resolution of the average received power patterns. Optimized pulses for two arrays are given. Numerical calculation results show that in comparison with Gaussian waveforms, disk arrays with optimized waveforms can provide considerable improvement in angular resolution.
