RADAR
 

Trying to equip the "Jap Submarine" TMO/RSRD with radar. Can't get SJ radar to detect them and can live with that, since subs were hard to pick up anyways. Reading up on the Batfish's encounters in Feb 45 where she sank 3 subs in 3 days, two boats were detected by the Batfish's radar warning equipment. This would be key to finding the boats(I've placed them in correct time and place and plan to places orders so player is patrolling the area in feb 45)

I recall removing Radar from Sampans and Junks that shouldn't have it years ago. Maybe if the Jap Submarine was listed in this file it could be added... just a thought.

I'd like to find out how to make SJ/SD Radar detect objects like my Sofu Gan, Sampans, & Submarines, and report them; "Radar Contact". If I go to the Radar I can see the pips, why doesn't my Radar operator report them? I don't see a pip for Sofu Gan though... was thinking of placing a patrol craft inside the model but haven't got around to it yet.

US Subs would use Sofu Gan to calibrate their Radar when entering Empire waters.

Yes certain landmarks such as sofu gan would be nice if could detect them on radar. Likley made it SJ does not detect land so it doesnt slow down game which is fine but should detect some things. They didnt even bother to put sofu gan in if you recall lol.


I recall various vessels having radar, I figure the jap can as well, just don't know how to make that happen.

A few Sampans etc. had radar in real life but not like SH4 or as early. It is the *.sns files for those boats in the Sea folder.

[Sensor 5]
NodeName=R01
LinkName=FuMO23 <------ !! to NULL .... lol
StartDate=19400301
EndDate=19451231

Here the dates may be right but when they have radar and shouldn't, this is how you do it. (above change LinkName= to NULL)

This is the .eqp file for the AI Jap Sub

Does it have a radar mast that is visible in the model but does nothing? Is it listed in the *.sns file for the IJN AI subs? If not, I wonder what would happen if you edited radar into the IJN AI subs *.sns file like this:

[Sensor 5] <<---- or whatever number is listed or not used in the IJN AI subs *.sns file .
NodeName=R01
LinkName=FuMO23
StartDate=19420301
EndDate=19451231

I haven't seen radar equipment on a Sampan of Fishing boat yet the *.sns radar entry gives them an alert beyond the 5 nm visual range alert... probably 8 - 10 nm?? (I haven't studied Jap radar distances)

This is way beyond my knowledge of the SH4 files, sorry.

It's worth a try.

Maybe give the lookouts on the IJN AI subs the power the IJN DD's etc have that spot you at 9,000 yards plus... lol

A bit beyond my current knowledge as well, why am asking lol.

Definitely don't want to up their visuals to the ridiculous levels RSRD has by default lol(run a mod to tone them down to reasonable levels). The whole idea is I can't get subs to show up on radar for some reason like other ships which is fine subs were tough to get on radar sets of the day. Batfish in Feb 45 would gain contact and lose it and regain. Relatively small ships sitting low in water and all.

There are no visible antennas.

Batfish sunk 3 subs in 3 days in Feb 45, two contacts were made first due to japanese sub's radar emissions, which Batfish closed in on then established radar contact. My thinking is give them radar in the sim in later years, help player close in. With my radar mod, they won't pick you up on surface until youre pretty close unless showing them your broadsides. My radar mod for enemy surface ships solves this.)

My two goals for ijn subs is to equip with radar and make them show up on SJ radar as well.

Yes, BATFISH is the only US sub to do this. In SH1 I was 'Sub killer' lol

What does Ducimus call his AI Jap sub? I've looked in the Sea folder and Roster in TMO 2.5.

You're partly responsible for getting AI warships to accurately fire torpedo's a few years ago, interesting topic I just read. Well done!

NSS AI Jap sub.

I am? I didn't know they ever got that figured out. Which thread are you referring to ? I need to implement this to my install.

I added a radar to the AI Jap sub. Will test soon.

The pictures - screenshots are gone now but here you are:

Original file is screwy however this may be it:

I hope you were successful with the radar

Lol I forgot about this somehow. Glad my idea spurred things into development.


I havent had a chance to test sub with radar out yet.hopefully soon.

For some reason single missions never show up, so have to do my testing in campaign sadly.

Ugh no instructions on install with download . Drives me crazy lol What do you mean the original file is screwy?

My download of AITorpedolauncher.zip a couple years ago is corrupt and won't open. I couldn't find it in the downloads section here.

Searching through the posts in the Topic I found these links:

http://www.mediafire.com/download/37b98xvnmxz7ugl/More+DDs+for+AITorpedoLauncher.zip

http://www.gamefront.com/files/24410898/AITorpedolauncher.rar

http://www.gamefront.com/files/23782530/AITorpedolauncher.zip

I had to re-boot my computer to get off the mediafire.com page, I think it was that one, maybe it was gamefront.com, but I don't have a virus - one of these sites wanted a username & password, plus they also wanted me to call Microsoft, they were trying to infect me!

Re-boots and virus/malware scans by 2 AV programs report I'm not infected. Also used Ccleaner.

Maybe someone here has AITorpedolauncher.zip or AITorpedolauncher.rar. The pictures I saved of AITorpedolauncher years ago in action look great. 'Hot, straight, and normal'.

Update. The radar works on the Japanese submarine now, they all showed up at historical time and locations where Batfish sunk them in Feb 1945. My RWR lit up when they were nearby, helped locate them in the night.

Downside is since they are at roughly same height as Us subs you have to take care or they will detect player sub and become tough to attack. Have them using type 21 radar as most escorts and smaller warships use in the sim, which has it's minimum height set to 7 meters.Profile matters , kept my bow pointed at one and he never detected me at 4,000 yards, if it were darker wouldve made a surface attack but went ahead and went for submerged attack.

Bagged all 3 subs.

Pretty excited this worked. Now to get them firing torpedoes lol .

The same thing happened to me on mediafire. Basically, it is now a "ScareWare" site. Trying to "scare" you into calling the phone number in the "Virus warning advertisement".

I also ran AV software after hitting that site and being unable to close that particularly obnoxious scareware window.

I usually download and run the FREE version of Kaspersky Virus Removal Tool as a full scan a couple of times a year and whenever necessary to complement my OS AV.

It is troubling that so many of our subsim contributor's files exist only on compromised sites such as Mediafire and others. I'm so happy that we have a download section right here on Subsim. Thanks Onkel Neal!

Really cool Bubblehead1980, that you got the radar running. We might have to liberally borrow from you!... :lol: - Have you tested to see if they can actually "see" your submarine with radar? Make their visual acuity next to nill and see if the radar detects you, and they attempt to avoid - or shoot!...

There are several version of the AI_TorpedoLauncher stuff, from Darkfish, jhapprich and pollyfiller (others??). I'm not sure if pollyfiller ever uploaded his version anywhere, but he had the launcher attached to submerged AI subs that shot at targets. s7rikeback is at this time attempting to attach them to the AI_IJN subs in FotRSU. We're expecting torpedoes to shoot, just not very accurately, since all of the launcher versions used a gun to do the shooting, and gun shots travel at a faster speed than torps can... therefore, the torpedo is actually shooting behind the target. I'm not sure it's worth much effort, unless a better aiming logic can be employed, but it'd still be cool.

Yes definitely the radar as I was well beyond visual range when he detected me and started zigging at 9 knots instead of traveling at 12 as I set them to do. If had spotted me, would have fired at me on deck gun as AI japanese sub does when spots player, never did fire, just started zigging and I dove to scope depth before visually spotted me, but did have me on his radar.

I followed the beam and found myself in a great set up for one of the attacks. I closed to 4,000 yards and kept my profile slim, with bow pointed at the radar signal. I could have probably got away with a night surface attack moonlight was a little bright so went for a scope attack.I was never spotted visually.

I am using my radar mod I uploaded, type 21 is set to surface only and type 13 is air only. I adjusted it so it's effectiveness vs subs is limited (as in real life) by adjusting it's minimum height, how the sub's profile to the beam is etc. Performance is pretty close to Japanese radar performance in real life, it's there, sometimes they detect, sometimes they dont . Can pull off attacks on convoys with radar equipped escorts, sometimes can't, they detect first. Thing is with subs, they are down on same level roughly as players sub, where as an escort and other ships are higher, sometimes they detect, sometimes they dont. I can get inside the screen undetected at times and even have traveled as part of he screen while sneaking in. My understanding is Japanese never had PPI screens but A scope type displays, so it was hard for them to tell. Closest I have been on a radar equipped escort undetected is 2900 yards, sure it was radar since it heavy fog and rain, I was trying to sneak in close and go for radar/sound shots on the merchants but was detected.

Batfish ambushed the japanese subs and if I recall, only one ever showed signs they knew Batfish was out there, others likely never detected Batfish on their radar.Their radars turned into homing beacons for Batfish.

I do believe, with a bit more testing, that CapnScurvy will have some news that will peak your interest in Radar against AI subs... a most interesting find... and with a very interesting potential work-around that is being tested. More later from the good Capn...

Lol teasing me with that one? Work around for what exactly?

Not sure about the radar detection, but it might be possible, with some "twisting"...

Not confirmed, so don't get your hopes up too high.
