Sentinel V Waves Array​ 

​​​ ​​​Array Type
Velocity in 3-6 bins and 4 beams plus surface 5th beam improves array geometry, allowing shorter waves in deeper water
​Janus
25°; lower variance and large aperture improves directional acuity​​

Number of Sensors​

13-25; more sensros = more robust​
Max Array Aperture

~0.84 x depth; large aperture improves directional functionality

​Smallest Lag in Array

~0.42 x depth; 5th beam provides short lags in the array for resolving higher frequencies

​Smallest Measureable Wavelength​

~0.84 x depth​​

Smalles Measureable Wave Period​

D=20m, P>3.3s D=50m, P>5.2s D=80m, P>6.5s
