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

Embodiments of the present application provide a beam control method and device, a beam control device, and a beam controller. The method includes: receiving a first control instruction sent by the electronic device, and determining the target antenna corresponding to the first control instruction according to the first control instruction. The azimuth scanning phase and the range scanning phase; the target antenna represents the antenna connected to the beam controller receiving the first control command; obtain the amplitude and phase compensation information of the target antenna in the InSAR system; the amplitude and phase compensation information Indicates information for compensating the amplitude and / or phase of the target antenna; based on the amplitude and phase compensation information, the azimuth scanning phase, and the range scanning phase, determine a beam control code of the target antenna; based on The beam control code controls the beam of the target antenna.

Description

A beam steering method, apparatus, beam steering device and beam controller technical field The application relates to the technical field of radar imaging, in particular to a beam steering method, device, and beam steering equipment and beam controller. Background technique Two-dimensional high-resolution radar imaging technology is often referred to as synthetic aperture radar (Synthetic Aperture Radar). Radar, SAR); spaceborne interferometric synthetic aperture radar (Interferometric Synthetic Aperture Radar, InSAR) system is built on the basis of spaceborne SAR technology and is a radar system based on interferometry technology; Aperture radar interferometry technology refers to the use of two or more SAR images under different incident angles that meet the interference conditions. The technology of inverting the three-dimensional topography, small changes or the properties of ground objects based on the generated interference phase or interference information....
