Correlation magnitude data give the magnitude of the normalized echo
autocorrelation at the lag used for estimating the Doppler phase change.
The Channel Master represents this magnitude by a linear scale between 0
and 255, where 255 is perfect correlation (i.e., a solid target). A value of
zero indicates bad correlation values.

Field Description
1-4 1,2 ID Code Stores the correlation magnitude data identification word 0200
(00 02h). LSB is sent first.
5,6 3 Range cell 1,
Field 1
Stores correlation magnitude data for range cell #1, beam #1.
See above.
7,8 4 Range cell 1,
Field 2
Stores correlation magnitude data for range cell #1, beam #2.
See above.

13 – 1028 7 – 514 Cells 2 – 255
(if used)
These fields store correlation magnitude data for range cells 2
through 255 (depending on the WN-command) for all beams.
These fields follow the same format as listed above for range
cell 1.
The echo intensity scale factor is about 0.45 dB per Channel Master count.
The Channel Master does not directly check for the validity of echo inten-
sity data.
