摘要

IEEE使用的远场定义来自窄带公式(时谐波场)。本文从宽带信号的角度探讨了远场的定义。提出了一种基于脉冲色散的大宽带相控阵远场时域定义。结果表明，时域远场的大小取决于信号的瞬时带宽。

Phased array far field in the time domain

The far field definition used by the IEEE comes from a narrow band formulation (time-harmonic fields). This paper looks at the far field definition from a broadband signal perspective. A time domain definition of far field in terms of the pulse dispersion for large, wideband phased arrays is presented. It is shown that far field in the time domain depends upon the instantaneous bandwidth of the signal.
