TFR over water

[vctpil]

Hi,

AFAIK, the raw video on the TF page should display a shadow area over water. Is it correct with the F-15E?

See the screenshot.

Thanks,

The TF radar has a fairly wide main lobe, 5.5° for 3dB attenuation, and first node at more than 10° diameter.

So in the view shown here, if you move a 10° disc over the hud, there is nowhere it can see water only, it will always pick land as well.

Then, you have the side lobes which are modelled as well.

It will be able to pick terrain height with sub-degree resolution only because of monopulse , which is perfect for this purpose. But when pointing at an area with water in the middle (no return) and land left and right, monopulse see the same as if it had a chunk of land in the middle.

Try over a wider water area I think you will have a gap.

Note that it also accounts for wind (but you have none, I can see this on UFC), water with waves will have radar returns.

For the efficiency of the "Bugs" subforum, it's better to discuss this first in the main forum and file a bug report only when you are sure it's a bug.

Thanks, nice explanation.
