[REQ] More Accurate Radar Screen

[Fish40]

I thought there was a mod out a while ago which offered a more detailed radar screen, with range rings. I find it difficult to measure range with the current layout. I'm useing RFB 1.4(not the latest version). The screen dose have bearing marks at 30 degree intervals, but without the range rings, you could only make an estimate.

I do want to say, that if the range rings were absent in reality, then I'll deal with the situation as I have been. Realism is numero uno!

No, you are correct in saying the radar display looked different in reality. Before 1.3 we could edit the PPI display, but so far now no one has been able to figure it out for 1.4 and 1.5.

To see what a real working SJ radar display looks like, check out these two pages. They are of the oldest working SJ radar set in existence, and it still works just like it did during the war:

Cool links Luke Thanks for that. From the looks of it, the real PPI scope had alot more bearing lines, but I couldn't make out if there were range marks on the screen. It didn't look like there were. If that's the way it was in reality, then it's OK with me It's amazeing to think that this unit still functions this well after so many years!

The only "range marks" one would see with the SJ radar would come from the range indicator display, like this one here (in the little rectangular window):

Which is one of the things SH4's SJ radar is missing.

I think you're confusing a recommended field mod with something that is generally available on all boats. Is there another example than the Cobia?

From the Radar Operator's manual: http://www.hnsa.org/doc/radar/part4.htm#pgSJ-1

Bearings and ranges may he read approximately from the PPI scope without stopping the antenna. It is possible to obtain target course within 5 degrees, and target speed within 3 knots from this data. The following suggestions will speed the obtaining of data from the PPI and increase the accuracy:


1. Add inked circles on the face of the PH tube for estimating range (four solid circles, interspaced by four dotted circles). Care must he taken not to scratch the tube in any way.

2. Improvise a more accurate 360 degrees bearing circle over which rides a cursor, or thread stretched across the screen. Targets may then he split by this thread and hearing read on the circle.

• From the same HNSA page (http://www.hnsa.org/doc/radar/part4.htm#pgSJ-3) there is a diagram of the same range indicator unit ("Figure 4 SJ-5. Range unit").

• USS Cod shows a range indicator unit for the SJ: http://www.usscod.org/graphics/CT-Sonar.jpg

• Pampanito has a range indicator: http://img.photobucket.com/albums/v2...JPampanito.jpg

• USS Croaker has one: http://glnmm.org/DSC00245.JPG

• USS Bowfin has one: http://img.photobucket.com/albums/v2...F/SJBowfin.jpg

• USS Ling has one: http://www.navsource.org/archives/08/0829716.jpg (hard to tell in that picture, but it's there)

Those are the ones I could find right now. I'm sure there's more pics at Navsource.

A mod was released to add more bearing lines and some range lines.

Version 2 is in the works, hopefully to include: higher resolution PPI scope, finer lines, bearing lines with numbers, arced contacts (instead of blobs), digital range readout, digital bearing readout and possibly a change to the radar sweep, depnding on what I find out about it.

Now we're talking! Glad to hear this. I'm useing the present version of your mod, and I just wanted to say that it is a great improvement over what we had (which was basicly nothing:rotfl. I can finally with some degree of accuracy, plot the course of a target useing the radar.Thanks again, and keep up the good work

Nigeis,

I didn't get any useful information from my Cobia contact. Sorry.

Wow, now that's what I, and I'll bet a lot of people, wanted to hear!!
I've always thought that radar was very underdeveloped in this game, so any improvement is very welcome!
