Quantity of every
scan
80 + ( (6 + 2) + (18 x e.g. 1000)) x e.g. 720 = 12,960,088 byte
2) Quantity in every hour
12,960,088 byte x 3600 sec. / 6 sec. = approx. 7.8GB (7,776,052,800)
3)
Quantity in 30 days
7,776,052,800 byte x 30 days x 24 hrs. = approx. 5.6TB

W (Doppler velocity width)
Range: 0 - 65535
Calculation formula
N is a recording level.
W[m/s]= (N-1)/100
W Range: 0.00 - 655.34m/s
Resolution: 0.01m/s
