Abstract
A novel L-band radiometer trading analog complexity for digital ditto has been designed and built. It is a fully polarimetric radiometer of the correlation type and it is based on the sub-harmonic sampling principle in which the L-band signal is directly sampled by a fast A to D converter at a frequency well below L-band. Stability has been a design driver, and the instrument is intended for airborne measurements of polarimetric sea signatures
