The Single Look Complex SAR format is a single look product of the focused signal. It means that the azimuth compression has been carried out using the full azimuth bandwidth and therefore contains the highest azimuth spatial resolution and at the same time, it suffers from maximum speckle. The data are in the radar geometry, i.e., in slant range coordinates, not projected onto any reference surface. Each pixel of the SLC product is a complex number. (i.e., has a real and imaginary component) that represents the amplitude and phase.
