Paolo Rocca, Nicola Anselmi, Mohammad Abdul Hannan, Andrea Massa

摘要:

本研究针对空中交通管制(ATC)雷达系统,设计一种锥形相控阵天线。该阵列采用全数字波束形成(DBF)结构,由等垂直模块组成,这些模块由线性稀疏阵列组成,能够在接收时产生指向不同仰角方向的多个瞬时波束。合成问题被投射在压缩感知(CS)框架中以实现天线复杂度(即,最小数量的阵列元件和/或射频组件)和辐射性能(即,一组参考图案的匹配)。为此,阵列元件的位置和每个波束的复杂元件激励的集合通过定制的基于CS的优化工具来共同定义。有代表性的数值结果,有关理想的以及真正的天线模型,报告和讨论,以验证所提出的设计策略,并指出设计的模块化稀疏阵列的功能,也与传统的阵列均匀间隔的元素。

英文摘要:

The design of a conical phased array antenna for air traffic control (ATC) radar systems is addressed in this work. The array, characterized by a fully digital beam-forming (DBF) architecture, is composed of equal vertical modules consisting of linear sparse arrays able to generate on receive multiple instantaneous beams pointing along different elevation directions. The synthesis problem is cast in the Compressive Sensing (CS) framework to achieve the best trade-off between the antenna complexity (i.e., minimum number of array elements and/or radio frequency components) and radiation performance (i.e., matching of a set of reference patterns). Towards this aim, the positions of the array elements and the set of complex element excitations of each beam are jointly defined through a customized CS-based optimization tool. Representative numerical results, concerned with ideal as well as real antenna models, are reported and discussed to validate the proposed design strategy and point out the features of the deigned modular sparse arrays also in comparison with those obtained from conventional arrays with uniformly spaced elements.
