摘要

相控阵馈电是射电天文学和微波接收机领域中一种先进的阵列接收技术。它相当于一个小阵列天线均匀地放置在射电望远镜的焦场上。通过后台波束形成网络，可以实现方向图合成、波束扫描甚至连续波束覆盖。时间调制阵列是一种通过时间序列调整阵列方向图和相位的四维阵列天线技术。虽然该技术主要应用于卫星通信和雷达系统，但它类似于相控阵馈电中由移相器和衰减器组成的模拟波束形成网络。本文以时间调制阵列技术为基础，将其应用于相控阵馈电的模拟波束形成技术中，并进行了相关仿真。

A Beamforming Method for PAF Receiver

Phased array feed is a advanced array receiving technology in the field of radio astronomy and microwave receivers. It is equivalent to a small array antenna evenly placed at the focal field of the radio telescope. Through the beamforming network at back stage, pattern synthesis, beam scanning and even continuous beam coverage can be realized. Time modulated array is a four-dimensional array antenna technology that adjusts the array pattern and phase through time series. Although this technology is mostly used in satellite communication and radar systems, it is similar to the analog beamforming network composed of phase shifter and attenuator in phased array feed. In this paper, based on the technology of time modulated array, it is applied to the analog beamforming technology of phased array feed, and the relevant simulation is carried out.
