Abstract

Synthetic aperture radiometer has the potential to meet the spatial resolution requirement of passive microwave remote sensing from space. A one-dimensional prototype of aperture synthesis radiometer at millimeter wave band is introduced in this paper. It contains 16 antenna elements, 16 receiving channels, 16 ADCs, and image reconstruction part. Error correction is made in the image reconstruction. Experiment results show the radiometer can give good images of natural scenes.
