摘要
摘要:致密焦面阵列馈源(DFPAF)融合了多喇叭多波束馈源和相控阵列馈源(PAF)的特点,与多喇叭多波束馈源和常规相控阵列馈源相比较,它可以同时提供更多的固定赋形波束进一步拓宽视场。在射电天文、雷达、电子侦察和卫星通信等领域引起了极大的关注。由于其阵列结构与常规阵列馈源不同,导致设计方法也具有特殊性,因此近年来展开了对其设计方法的研究。该文充分利用反射面天线的固有特性,并结合阵列天线理论,提出一种可以快速、稳健地设计致密焦面阵列馈源的方法,给出了设计原理和设计结果,并和最具代表性的多喇叭多波束馈源进行了性能对比分析,为设计致密焦面阵列馈电的大型反射面提供理论和数据参考。

Abstract:The Dense Focal Plane Array Feed (DFPAF), which integrates the characters of multi-beam feed with multiple independent horns and Phased Array Feed (PAF), can simultaneously provide more fixed shaped beams and wider field of view than multi-beam feed with multiple independent horns and PAF. It attracts more attention in radio telescope, radar, electronic reconnaissance, satellite communication and so on. Its unique structure promotes the studies on special design method recently. Combing the theory of array antenna and inherent characteristic of parabolic reflector antenna, a fast design method with robust processing procedure is proposed in this paper. The design principle, calculated results, and comparison between DFPAF and the most representative multi-beam feed with multiple independent horns are presented. All these provide a theoretical basis and reference data for the design of giant reflector with DFPAF.
