Abstract

Different from linear arrays that can resolve only one angular component, two-dimensional (2-D) array patterns enable to remove the cone of uncertainty and right/left ambiguities generated in a linear array. Motivated by this, a novel structure of 2-D time-modulated planar arrays (TMPAs) is developed to synthesize directional modulation (DM) symbols in this paper. The proposed 2-D TMPA DM transmitter can synthesize multicarrier DM symbols with suppressing the mirror harmonic frequencies and provide a higher power efficiency. This is demonstrated by way of simulations of a multi-beam 8*8 element planar antenna array and its security performance is shown via the bit error rate (BER) metric.

支持定向调制符号合成的时间调制平面阵列

与只能分辨一个角度分量的线性阵列不同，二维（2-D）阵列模式能够消除线性阵列中产生的不确定性锥和左右模糊性。受此启发，本文开发了一种新型的二维时间调制平面阵列（TMPA）结构，用于合成定向调制（DM）符号。所提出的二维 TMPA DM 发射器能在抑制镜像谐波频率的情况下合成多载波 DM 符号，并提供更高的功率效率。本文通过对多波束 8*8 元平面天线阵列进行仿真来证明这一点，并通过误码率 (BER) 指标来显示其安全性能。
