In this chapter the processing of step M_READFILES is described. It can be selected by a PROCESS M_READFILES line in the input file. This is the first step if the ERS1/2 SLC images are processed.

The SLC leader, volume and (header of the) data file are read, and relevant parameters are written to the master result file specified by the general card M_RESFILE. These parameters are used in the further processing. Currently, ERS1/2 SLC and ENVISAT SLC files can be read. If the output of this step is mimicked, Doris can be tricked to process the other steps. The sole purpose of this step is to create result file where relevant parameters are stored (PRF, wavelength, etc.), also see the example in the next section.
