I do like (:,1) but it only gives me a struct 1x1 that contains the first row with the 3 fields but I need only the first field (first column) with all the 84 elements in column.

Thank you

After you read this link, attach your structure array in a .mat file.

In the meantime, try

output = vertcat(s.fieldYouWant);

Try this:

s = load('Tailwind_satE08.mat')
DETECTION = s.DETECTION
% Extract into 3 separate variables.
ranges = [DETECTION.Range];
Doppler = [DETECTION.Doppler];
TxPOS = [DETECTION.TxPOS];
