提出了一种适用于频率分集阵列（FDA）天线系统的距离-角度相关波束形成方法。与传统的相控阵天线不同，FDA天线采用与跨阵列元件的载波频率相比少量的频率增量。频率增量的使用产生作为范围、时间和角度的函数的天线方向图。距离-角度相关波束成形允许FDA天线在期望的范围或角度上发射能量。这提供了抑制距离相关的杂波和干扰的可能性，这对于传统的相控阵系统是不可访问的。本文建立了FDA雷达信号模型，通过分析发射/接收波束图和输出信号干扰噪声比（SINR）性能，研究了距离-角度相关波束形成性能。广泛的模拟实例和结果。
This paper proposes a range-angle-dependent beamforming for frequency diverse array (FDA) antenna systems. Unlike conventional phased-array antenna, the FDA antenna employs a small amount of frequency increment compared to the carrier frequency across the array elements. The use of frequency increment generates an antenna pattern that is a function of range, time and angle. The range-angle-dependent beamforming allows the FDA antenna to transmit energy over a desired range or angle. This provides a potential to suppress range-dependent clutter and interference which is not accessible for conventional phased-array systems. In this paper, a FDA radar signal model is formed and the range-angle-dependent beamforming performance is examined by analyzing the transmit/receive beampatterns and the output signal-to-interference-plus-noise ratio (SINR) performance. Extensive simulation examples and results are provided.
