摘　　要：推导了基于高斯脉冲的一维超宽带阵列的时域辐射信号表达式,分析了阵列最大辐射方向与网络延迟、阵元间距的函数关系,提出了辐射信号合成波形宽度与辐射方向的近似函数关系式,仿真分析了阵列辐射波形与阵元数、阵元间距、辐射脉冲宽度、斜距、网络延迟等参数的依赖关系。同时指出信号宽度参数是估计雷达与目标相对角位置的可用信息,对近程超宽带冲激引信的研究有重要参考价值。The expression of time domain radiation waveform of 1D array is introduced based on the Gaussian pulse. The relation between the angle value of the maximum radiation direction and the time of network delay, the space between adjacent elements of array antenna is discussed. The approximate function relation between the duration of compositive waveform and the angle value of radiation direction is put forward. Some available results have been obtained through simulation and calculation. It is founded that the radiated waveform is in relation with the numbers of array elements, the space between adjacent elements of antenna, the duration of the radiated pulse, the radiation distance, the difference of delay time of adjacent array elements. The duration of compositive waveform can be regarded as useful information for target direction detection, and it is very important for studv on short range UWB impulse fuze.
