Abstract

The invention provides a method for generating a multiband angle feature map, which comprises the following steps of: acquiring a plurality of two-dimensional synthetic aperture radar (SAR) images of a ground object target, the plurality of two-dimensional SAR images comprising two-dimensional SAR images of different bands or azimuth angles, and the two-dimensional SAR images comprising feature points; according to the feature points, mutually registering and fusing the plurality of two-dimensional SAR images to obtain a fused two-dimensional SAR image; mapping different colors to different wavebands or azimuth angles to construct a color picture; and combining the color picture with the fused two-dimensional SAR image to generate a multiband angle feature map of the ground object target. The invention further provides a multiband angle feature map generation device, electronic equipment and a computer readable storage medium.

Description

technical field [0001] The present invention relates to the technical field of radar signal processing, in particular to a method, device, equipment and storage medium for generating a multi-band angle feature map. Background technique [0002] Synthetic Aperture Radar (SAR) imaging technology is an important technical means for high-resolution earth observation. However, the acquisition of traditional SAR imaging data is limited in observation dimensions such as bands and angles, resulting in unclear, unrecognizable, and difficult to interpret acquired targets, which seriously restricts the application benefits of SAR data. Therefore, with the development of SAR system technology, the multi-dimensional information acquisition capability of SAR is continuously improving, and it is extending from a single observation dimension of polarization, angle, and frequency to the synthesis of multiple observation dimensions such as multi-angle, multi-band, and multi-polarization.
