Provided are a scattering aperture imaging method and a device, a system and a storage medium. The method mainly includes four steps of scattering point position estimation, azimuth resampling, range compensation and synthetic aperture radar imaging. A phased array radar with a fixed position is used for NLOS imaging, and the radar can control a beam to scan in space, which is equivalent to a scattering aperture moving along a relay surface. Therefore, the method can realize converting NLOS imaging into LOS synthetic aperture radar imaging, which can be suitable for the situation that a relay surface is rough and the relay surface with more complicated surface condition, thus widening the application range of radar NLOS imaging.
A scattering aperture imaging method, wherein in a situation that a phased array radar faces towards a rough relay surface, a projection of a beam main lobe of the phased array radar on the rough relay surface is regarded as a virtual aperture, and scattering of a radar signal on the virtual aperture is equivalent to scattering of the radar signal occurring at a scattering point in the virtual aperture, the virtual aperture being a scattering aperture and the scattering point being a main scatterer, and the scattering aperture imaging method comprises:
