相控阵天线以其高效电子控制波束的能力而闻名，但对于所有范围单元来说，波束控制都是固定在一定角度的。本文回顾了频率不同阵列 (FDA) 天线。与相控阵不同的是，与载波频率相比，FDA 在阵列元素上使用较小的频率增量。使用频率增量生成一个阵列因子，该因子是角度、时间和范围的函数，允许 FDA 天线在所需的范围和角度内传输能量。除了分析 FDA 因素特征外，本文还研究了 FDA 在范围依赖型能量控制中的潜在应用以及系统实施中的技术挑战，旨在呼吁 FDA 进行进一步的调查。
Phased-array antennas are known for their capability to electronically steer a beam with high effectiveness, but beam steering is fixed in an angle for all range cells. This paper reviews frequency diverse array (FDA) antennas. Different from a phased array, an FDA uses a small frequency increment, as compared with the carrier frequency, across array elements. The use of a frequency increment generates an array factor that is a function of the angle, the time, and the range, allowing the FDA antenna to transmit the energy over the desired range and angle. In addition to analyzing FDA factor characteristics, this paper investigates FDA potential applications in range-dependent energy control and technical challenges in system implementation, with an aim to call for further investigations on the FDA.
