摘要

采用对数频偏的分频阵列可以产生与距离角相关的非周期波束。本文采用基于二项式级数展开的对数函数频偏来提供聚焦的FDA发射波束图。与传统的单载波对数偏移相比，该方法可以在特定目标位置引导能量，方向性增强。因此，仿真结果证实了改进的目标定位。

Binomial Series Expansion of Frequency Offset for Synthesis of Frequency Diverse Array Beampattern

Frequency diverse array using logarithmic frequency offset can produce a range-angle dependent non-periodic beampattern. In this paper, a frequency offset of logarithmic function based on binomial series expansion is used to provide a focused FDA transmit beampattern. Compared with the conventional single carrier logarithmic offset, the proposed method can steer energy at a particular target location with enhanced directivity. Simulation results, thus, corroborate improved target localization.
