CINECA IRIS Institutional Research Information System
IRIS è la soluzione IT che facilita la raccolta e la gestione dei dati relativi alle attività e ai prodotti della ricerca. Fornisce a ricercatori, amministratori e valutatori gli strumenti per monitorare i risultati della ricerca, aumentarne la visibilità e allocare in modo efficace le risorse disponibili.
EnglishThe authors address the problem of focusing synthetic aperture radar (SAR) images for wide azimuth angle of observation. In these applications a second order polynomial approximation does not accurately fit the phase term due to the platform motion. Therefore, image focusing requires higher order polynomial approximation. The authors propose a simple and effective autofocusing method based on the contrast optimisation of the image. They also present and discuss simulation results to illustrate the effectiveness of the method

| Abstract: | The authors address the problem of focusing synthetic aperture radar (SAR) images for wide azimuth angle of observation. In these applications a second order polynomial approximation does not accurately fit the phase term due to the platform motion. Therefore, image focusing requires higher order polynomial approximation. The authors propose a simple and effective autofocusing method based on the contrast optimisation of the image.
