一种扩大8 mm波段综合孔径辐射计成像视场的方法
A method to enlarge the FOV for 8 mm band synthetic aperture radiometer
摘要
Abstract
The field of view (FOV) of the 8 mm band synthetic aperture radiometer with regular Y-shaped array is small due to the relative large electronic scale of the RF front.To overcome this disadvantage, a kind of star-shaped array is presented.In the star-shaped array, the visible distance is only half of that of the antennas, so it doubles the imaging FOV.To deal with the missing visibilities of the star-shaped array, an image restoration method based on back-dropping and projecting onto convex set (POCS) is presented.Imaging simulations were carried out.The simulations validate the effectivity of the presented method.关键词
