High resolution radar imaging of urban areas
WebDec 13, 2024 · High Resolution Multipass Airborne SAR Tomography in Urban Areas Abstract: This As classical tomographic synthetic aperture radar (TomoSAR) imaging techniques, the spectral analysis and compressive sensing (CS) have been applied on a large quantity of applications. Webhigh-resolution satellite imaging of urban areas. This paper reviews past and current research and proposes a solution to the problem of automatic detection and removal of shadow features. Tests show that although detection and removal of shadow features can lead to improved image quality, results can be image-dependent. Introduction
