Problems solved by technology

[0003] In related technologies, most SAR systems use digital array antennas, and the beam controller is an important part of the SAR system; for the InSAR system with a single platform and two antennas, since the beam controller in the system cannot compensate the amplitude and phase of the antenna Information controls the beam of the antenna, which will increase the interference error between SAR images, and then reduce the imaging accuracy of the InSAR system

Abstract

The embodiment of the invention provides a beam control method and device, beam control equipment and a beam controller. The method comprises the steps that: a first control instruction sent by electronic equipment is received, and an azimuth scanning phase and a range scanning phase corresponding to a target antenna are determined according to the first control instruction, wherein the target antenna represents an antenna connected with the beam controller receiving the first control instruction; amplitude-phase compensation information of the target antenna in the InSAR system is obtained, wherein the amplitude-phase compensation information represents information for compensating the amplitude and / or phase of the target antenna; a beam control code of the target antenna is determined based on the amplitude-phase compensation information, the azimuth scanning phase and the range scanning phase; and the beam of the target antenna is controlled based on the beam control code.

Description

technical field [0001] The present application relates to the technical field of radar imaging, and in particular to a beam control method and device, a beam control device and a beam controller. Background technique [0002] Two-dimensional high-resolution radar imaging technology is usually called Synthetic Aperture Radar (SAR); the spaceborne interferometric Synthetic Aperture Radar (InSAR) system is based on spaceborne SAR technology and is a The radar system of interferometry technology; among them, the synthetic aperture radar interferometry technology refers to the use of the interference phase or interference information formed by two or more SAR images meeting the interference conditions at different incident angles to invert the surface three-dimensional terrain, microscopic The technology of changing or feature properties. It can be seen that compared with the traditional single-platform single-antenna SAR system, the single-platform dual-antenna InSAR satellite ...
