This is the data format of WERA raw data which is stored on the
Unix/Linux workstation controlling the WERA. To distinuish .SORT data from
other data formats, the header contains the code '
FMSOCO' [Frequency Modulated
SOrted phase COrrected]. Due to a selectable number
of SAMPZ samples,
number of ANT antennas,
and number of NRRANGES range cells,
the size and the internal data structure varies. All information needed
to adopt the processing programs to this varying data format is taken from the
header. The header also contains information
on the Mode Bits (description)
and the HZMode Bits (description)
which have been set during the measurement.
The structure in each data file is as follows: | | RC=1 | RC=2 |..| RC=NRRANGES | | HEAD |----------------------------------|-----------------------------|..|------------------| | | Ant=1 | Ant=2 |...| Ant=ANT | Ant=1 | Ant=2 |...| Ant=ANT |..| .......| Ant=ANT | | | t=1..SAMPZ | ... |...| ... | ... | ... |...| ... |..| .......| ... |Each timseries T(RC,Ant) consists of t=1..SAMPZ complex samples (I,Q) [IEEE REAL*4,IEEE REAL*4] with a distance in time of RATE. File_Size [Bytes] = 512 + 8 * SAMPZ * NRRANGES * ANT |
The header also contains information on:
