摘要

时间调制阵列(tma)通过其谐波模式的自适应波束形成来实现角分集，其优点是采用单个射频(RF)前端。在tma中通常使用的矩形脉冲并不能有效地将频谱能量分配到所利用的谐波中。我们提出了一组脉冲，即所谓的加权余弦和(SWC)，尽管其形式简单，但它允许在打开多模TMA大门的同时，对所涉及的谐波进行灵活的窗口。

Time-modulated arrays with Sum of Weighted Cosine pulses

Time-Modulated Arrays (TMAs) perform angular diversity through the adaptive beamforming of their harmonic patterns with the advantage of employing a single Radio Frequency (RF) front-end. Rectangular pulses typically used in TMAs are not the best ones to efficiently distribute the spectral energy among the harmonics exploited. We propose a family of pulses, the so-called Sum of Weighted Cosines (SWC), which despite its simple form, allows for a flexible windowing of the harmonics involved while opening the door to a multimode TMA.
