Field imaging experiments by a prototype super-synthesis radiometer

The super-synthesis radiometer is a synthetic aperture radiometer. The authors made a prototype super-synthesis radiometer. The radiometer has 17 interferometers of 6.6 GHz. The imaging experiments were done in the field of an antenna open-area site. The radiometer moved on a circular arc lifted by the arm of a crane truck. The behavior of the radiometer to an extended target is numerically evaluated to interpret the experimental results. By the experiments unknown radiation was found in the lawn area
