The effect of fluctuations in signal phase on the measurement properties of synthetic-aperture radar
Abstract
It is noted that errors in determining distances and the dimensions of objects on the basis of coordinates in synthetic-aperture radar arise mainly from geometric distortions in the radar image, distortions that in turn derive from spurious fluctuations in the signal phase. The correlation function of these distortions is determined here, noting that allowance must be made for this function in assessing the measurement errors. The method outlined makes it possible to determine the correlation functions for the displacement of the 'center of gravity' of the signal function.
