Radar questions

[merc4ulfate]

It will depend on the mods you run. Some mods will replicate with some degree of accuracy what each side had and it will all depend on what year it is.

Early in the war no radar. Mid way the Americas were more advanced but by the end both sides had radar and radar detection gear so if your using your radar they could see that you were and home in on you.

All of this is is replicated by different mods and the better of them will do so at accurate time periods during game play.

The same goes for hydrophone and sonar detection.

If your surfaced and the enemy has radar at that time and your in that devices range you will be seen.

It will do you well to learn history.

Thanks but at this point i ask, will the enemy see me only when my radar is on or even when it is off?

(I'm assuming your sensors and ai equipment are stock 1.5, as shown in your intro)
They can see you using their inferior radar, but they can also detect radar transmissions in some mods. There's been quite a bit of debate over the existence and effectiveness of Japanese radar detection. But historicaly, early war is fine, the Japanese racist thinking of the time concluded they had incredibly good eyesight, so they trusted too much in lookouts, 43+ you see radar sets become more and more common. Now if we look in the .sns (sensors) files we can deduce that CO1 is radar detection, and if you go through the Japanese Escorts you can see it's marked null for them.

Running good mods will model more effectively the use of sonar and radar from all combatants. Some find the game to hard to play with realistic sensors but I find it makes for a much more challenging confrontation.

Okay, let's check the scorecard:

Your radar is on. What do you know? You know their exact position, course and speed, and you know exactly when that changes and what their NEW course and speed are. You have the complete keys to the city.

Now, what do they know? We'll assume they have radar detection gear and they detect you. "Shazzam! There's something out there somewhere running a radar set."

Now you tell me is it's worth it to run the radar if you think you're going to be detected. The answer is HELL yes. Run that puppy ragged.

The exact situation came up when Captain Joe Enright's Archerfish (the only US submarine whose name was changed by her crew, by the way!) saw this island moving on his radar. A bright crewmember suggested he turn the radar off and Enright made the same assessment as I just made.

But he was wrong. Detecting the radar, Admiral Abe of the Shinano concluded that anyone brazen enough to run radar must be part of a vast wolfpack of submarines, so instead of maintaining his invincible straight line speed where he was untouchable, Shinano started a zig pattern--right into the jaws of Archerfish. Radar being detected was the death of the largest target ever sank in WWII.

I'd say the score is advantage submarine and you should run the thing all the time.

RR, your analysis overlooks one small but important fact. The strength of a radar signal varies inversely with the square of the distance, while the strength of the radar return varies inversely with the fourth power of the distance. Assuming that the receiver of your radar set is just as sensitive as the receiver of his detector, then he will detect your emission at four times the range at which you detect him. That's why modern radar detectors way outrange the radar sets themselves, and why modern doctrine stresses use of passive systems.

Now, it's certainly true that the USN had technically superior electronics, so the assumption of equal sensitivity is probably invalid. And a large target - like Shinano - would give a powerful return. But the physics is always on the side of the detector. Think of looking for someone at night using a spotlight. No matter how bright the light, he will see your light long before you can see him. When the enemy may have effective radar detection capabiliy, it is always prudent to limit your own emissions as much as possible. The Viet Nam era axiom applies: "He who lights up first, gets smoked."

I think you're right on paper except that the height of the antenna was such that maximum detection range and the horizon matched up.

So while it's possible to detect SJ-1's beams out to 50 miles or so on paper, it can only actually start picking up the top of a BB at 12 miles and vice versa due to line of sight through the surface of the ocean..

Then again, depending on how the beams bounce... I don't actually know the answer to that at all.
