I'm not aware of that being a specific style of tent. That is simply a shade created without the use of trees, and can very easily be created with:
20' x 10' tarp
8 adjustable height poles
8 dishes/flat pads for the foot of each pole to prevent the poles from just sinking into the sand
Cordage to use as guy lines of varied length
8 (minimum) anchor points, such as stakes. (These would need to be chosen with consideration for terrain, and should NOT be typical stakes found with most retail purchase tents)
Your main concern for the picture above is how to gain purchase into the soft sand to overcome the forces of wind with that big sail of a tarp. The tarp should have many sewn in loops for tie points (at least 5 per short side and 10 per long side, as well as at least 5 in line in the field of the tarp, dividing the length into quarters).
If your area of use has high wind, then I'd use a little different approach, two 10' x 10' tarps, a sturdy ridge line down the center and overlap the edges in the middle, with the flap on the lee side of the wind going beneath the other flap. That configuration will allow a vent of air pressure at the peak/ridge, defeating the "parachute" affect of having a single cloth, yet still shedding rain.
