Abstract :
Synthetic Aperture Radar (SAR) Self-Focusing post-processing techniques can be used for faster higher precision Phase Noise and Allan Variance measurement on more than one signal component at a time. Software Radio (SDR) techniques [1, 2] are used to sample, acquire decimate and process the signals, on a continuous basis, for record lengths of up to a few days and with resolution bandwidths down to a few milliHerz.
