WERA SCAN Data (.RAW)

This is the data format of WERA SCAN data. The data structure is identical to those of the WERA RAW data (.RAW). The following information is also encoded in the header of each SCAN data file:

The Date and Time includung the seconds SS of the acquisition start time,
the TAU duration of the frequency scan, fixed to 1.876875 seconds,
the MT length of a frequency scan, fixed to 11088 samples,
the NFFT number of frequency scan, fixed to 32 scans,
the NANT number of antennas, and
the Mode Bits during SCAN measurement (info on Mode Bits)
the HZMode Bits during SCAN measurement (info on HZMode Bits)

The structure in each SCAN data file is as follows:

|      |        Chirp_number=1          |        Chirp_number=2        |..| Chirp_number=NFFT |
| HEAD |--------------------------------|------------------------------|..|-------------------|
|      | ANT=1   | ANT=2 |...| ANT=NANT | ANT=1 | ANT=2 |...| ANT=NANT |..| .......| ANT=NANT |
|      | t=1..MT |  ...  |...|   ....   |  ...  |  ...  |...|   ....   |..| .......|   ....   |

Each [Chirp_number,ANT] data set consists of 2*MT INTEGER*2 (16 bit signed integer) values, which form MT I/Q pairs for a complex FFT.
