How do you determine AOB without the length of the boat?

Yeah, but RADAR from WWII wouldn't give you the pin point accuracy that it does in game. Just look at the surface scope and see how accuratley you could judge range to target based on that.

If I am not mistaken, the SJ radar had a separate readout that gives you range down to the yard, so it's pretty accurate in that respect.

Radar was the gold standard for range, with even sonar taking a distant second.

now if only we could get radar to work while submerged to periscope depth :hmm:

[Quillan]

You can come up to around 35-40 feet depth (radar depth) and it works just fine.

Yes, I'm familiar with 'radar depth' up to 38 feet in calm seas. problem is, most the time my seas aren't calm and I do good to have working radar up to 25 feet depth, thats barely decks awash and in some cases it isn't.

It's a good time to try out my Nav Map and Plotting Tools Video in controled conditions. Please check it out and comment here. I need some more tools for making these and maybe I can make 'em better. For now I just want to know if there is anything I left uncovered that you'd like to know about.

Throwing a wrench your way.

Link fixed at http://www.subsim.com/radioroom/show...80&postcount=1
First link under Rockin Robbins' Lnks. Lotsa other stuff to see there too.

denny927, been using the SubSim search engine a lot haven't you?!

Optical Targeting Correction puts the ships length onto the Recognition Manual.




The only problem using it before OTC was there was no way of accurately measuring length of a target given the inconsistencies of the games resolutions. The OTC thread explains what each player's game resolution does to the periscope or TBT views.

In a nutshell, the measurements of the Telemeter divisions (the hash marks on the periscope or TBT scopes used for measuring) are not consistent for every player's game setup. What is accurate for one players periscope view, isn't accurate for another. Nor is the periscope measurement, consistent with the TBT/UZO measurement. The point is the stock game, TMO, RFB, and any other mod the game has, doesn't address the problem of having accurate measuring periscope or TBT Telemeter divisions to help in finding range, or using length to determine AoB of a target.

Optical Targeting Correction does.

Also, since some of this thread referrers to the use of radar, OTC reworked that as well. The following image has the OTC PPI radar screen showing a target blip at about the 3000 yard range (at the lowest 8000 yard distance setting of the unit), and at about a 12 degree relative bearing. Good enough to make a plot of the target on the Navigation Map for future firing solution figuring.

The 3000 yard range could be used to input the range figure into the TDC with the OTC "Range Dial" that's a part of the Attack Data Tool on the periscope screen. As in real life, the "range to target" gleaned from the radar screen, could be placed into the TDC without use of the Stadimeter, or Sonar input.

The image is not a close-up of the radar screen. It's the actual size in-game, with the radar screen zoomed in (a new feature) and the HUD dials deleted from view for the sake of taking the picture.
