摘要

我们提出了一种用于单脉冲雷达的可重构环形阵列天线掩模约束功率合成的新方法。通过使用轨道角动量涡旋光束，并且不增加波束形成网络的复杂性或相对于最先进的解决方案的信号处理时间，所提出的方法可以提高相对于通常技术的指向精度。将整体综合化为一个以尽可能减少阵列控制点数量为目标的凸规划优化问题，并在相关应用场景中进行了测试。

Four-beams-reconfigurable circular-ring array antennas for monopulse radar applications

We propose a new approach to the mask-constrained power synthesis of reconfigurable circular-ring array antennas for monopulse radar applications. By resorting to Orbital Angular Momentum vortex beams, and without increasing either the complexity of the beam forming network or the signal processing times with respect to the state-of-art solutions, the proposed method allows improving the precision pointing with respect to usual techniques. The overall synthesis is cast as a Convex Programming optimization problem aimed at reducing as much as possible the number of control points of the array, and it is tested in relevant application scenarios.

期刊介绍： Radio Science (RDS) publishes original scientific contributions on radio-frequency electromagnetic-propagation and its applications. Contributions covering measurement, modelling, prediction and forecasting techniques pertinent to fields and waves - including antennas, signals and systems, the terrestrial and space environment and radio propagation problems in radio astronomy - are welcome. Contributions may address propagation through, interaction with, and remote sensing of structures, geophysical media, plasmas, and materials, as well as the application of radio frequency electromagnetic techniques to remote sensing of the Earth and other bodies in the solar system.
