Kilo sensors

I just happened to have several scenarios I used to test sonar performance in bad acoustic conditions set in the Persian Gulf using a sand bottom.

I picked up a fishing boat on the kilo hull array going 10kts at 4.3 nm. Pretty bad, but bad within specs.

Cheers,
David

PS Also, in 1.03 the acoustic model simulates bottom bounce and other things not seen at all in 1.01. It took some time for us skeptical old timers to buy into the 1.03 model, but its really good. Even a SW with a TB-29 won't see a fishing boat or even torpedo up close if it is under a layer in 1.03, depending on the particulars of the situation.

He was going 3 knots....it was wild to see him easily at 8x visually and not a peep acoustically.

Actually Flat sand bottom is one of the best for Bottom bounce profile!

I was going to say...

Sometimes I worry a lot of the nuance of sonar gets lost in the environmental model.
