As a former air defense radar operator and currently an air traffic controller I can tell you radar is very strange. Only trained operators can distiguish between garbage, birds, ships, aircraft, tractor trailers ... Nothing like watching 18 wheeler tractor trailers on a radar that's designed for aircraft !!!! Here's a good Radar Tutorial link I found on the web, some parts are in German : http://www.radartutorial.eu/index.en.html Note: Side by side comparison of Ducimus' drawing and a drawing of the isotropic radiation from above link : |

I erased all my campaign files, just started at 1941, picked up a Porpoise, upgrade an SD, i am sure i have nothing more related to radar only an SD. Your file still catching ships, i live with this, and.... the bad, no detect planes when your sub is heading south, 090-270. Have you the same problem or it is me We are at start point... |

I haven't tried it yet (working mid shift tonight .. need sleep). Reset the ElevationMax to 181 and have another shot. Appears ElevationMax might need to fall between 181-360 . Leave the ElevationMin at 2.5 . |

Hmmm... I give up..
In my test mission, everything works as advertised... mostly... It is strange that things work one way in one mission and not in another.. Then I enter a campaign, and I get the same.. ships, not all the time, but sometimes... TopCat reported this, you have reported this and now I see it. The problem is when you think you found a fix, you havent!!!! Could it be time compression - realistic sensors should be on too maybe.. Could be anything.. |

One reccomend, just take the job to start a new campaing every tes, anoying, but may be save files can bring problems. I arrive to a point where all works fine, except by the SD still catching ships. May bewe need to live with this issue... Still on job... |

Well ... still testing and :
Some SJ radars had the same problem than the SD radar, not contacts when your sub heading point to south 090-270.... Check S-18, S-42 subs into stock missions as Battle of Fillipines I will attempt to made same changes than into SD.... |

I had another intesting idea. From earlier tests I noted that when you increase MaxRange you also increase the distance that the contact appears. I'm thinking that the unknown angle that Ducimus can't find might actually be the Cotangent of MaxHeight divided by Maxrange. When I get home in 7 hr's I'll try the default SH4 v1.2 setting with a new Maxrange of 900,000 meters. Very interesting.:hmm: |

I forgot in the fisrt tweaks of this topocs we change both SD and SJ. I concentrate into SD and forget the SJ. The question is ...why we need to pass beyond 180 ?? Quote:

Node height affects it too. because the P-Class rides out the water so much, I lowered it by modding the surfaced depth in the sim file. That has affected radar reception. While other classes are fine, my P-class no longer picks up SD contacts at 2.5/177.5...
Changing some variables makes this process boat specific. Thats why some of my tests were screwy. I still think raising the elevation to a cone is the best way to do it. I may need to move some sensor nodes on my boats though. I will test with early Gato from now on, as the P-Class node is too low after I lowered the boat.

I did a little testing of my own and as usual came up with nothing conclusive.
A couple observations: Quote:
Another thign i noticed was that after decreasing the MinSensorHeight from 0.2 to 0, a MinHeight change from 8.3 to 9 was still able to pick up aircraft on a Gato. If i remember correctly, before, 9M min height broke air contacts. Hence the 8.3 settings. Increasing it past 9, it no longer worked. I had a halfassed idea to try a minSensorheight of -0.2 and increasing the min height to 10, just to see if it would work. Probably would, but we'd be back to the same problem as before. But, its as if this sucker is acting as an umbrella, with the minSensorHeight being the very bottom edge of that umprella. Changing SD to RWR. Ive tried again, twice, two different ways. Not working. At this point im ready to just reduce SD radar to a distance of like 10 meters so it no longer detects anything at all, and then increase SJ radar geomety so it picks up everything. Because at least then i could turn the bugger off when returning to port instead of getting spammed by all the contacts. With the SD radar behaving the way it is, and as so far being unable to find a solution to make it work as advertised, there really isnt much of a point in having it in the game in my opinion. |
