Abstract

The invention discloses a single pulse wide angle electric scanning reflective array antenna comprising a reconfigurable reflective array surface (1), a polarization grid (2), a bias voltage circuit (3), a wave control machine (4), a control processor (5) and a feed source subsystem (6). The size of the caliber of the polarization grid (2) is equal to that of the caliber of the reconfigurable reflective array surface (1), and the polarization grid (2) is positioned above the reconfigurable reflective array surface (1). A radiation aperture surface of a feed source (61) is parallel and level to the reconfigurable reflective array surface (1) and is positioned at the center of the reflective array surface. The single pulse wide angle electric scanning reflective array antenna adopts a spatial feed mode, that is to say, the feed source irradiates the polarization grid and feeds the array surface after reflection. A polarization grid structure is applied to a reconfigurable reflective array antenna, and the feed source, the polarization grid and the reflective array surface form a double reflective structure, therefore, the performance of an antenna structure is excellent, the antenna structure can facilitate the installation of an antenna port and the connection of the antenna port and a radar system, and the antenna is compact in structure with a low section.

Description

technical field [0001] The invention belongs to the technical field of antennas, in particular to a low-profile single-pulse wide-angle electric scanning reflector array antenna. Background technique [0002] With the continuous development of antenna and radar technology applications, related space science and applications continue to expand and deepen, and there are more and more requirements for the functions that the wireless system can complete, which requires the antenna in the system to have the ability to realize multiple functions Or it can achieve corresponding performance indicators according to different applications. Simply increasing the number of antennas to increase antenna functions or performance can no longer meet the requirements of more and more complex space missions, and the development of antenna reconfigurable technology is a way to deal with this problem. [0003] In order to meet the requirements of complex and diverse radar working modes, the ante...
