I don't understand how radar works. npc and player ships disappear from the radar for no reason.

Recently, I created an entry on the issuetracker website.

In the post I asked for a review of the radar system of our ships, since when we decelerate in super cruise to minimum speed the enemy ships disappear from the radar, both npc and players.

The post has been marked as repeated and has been rejected. I have looked for the post that started the problem and it has also been closed.

It explains how the radar works and why the ships disappear.

Greetings commanders,

We will be closing this issue as it works as intended. The sensor detection works based on emissions - at low speeds emissions are very low, and it's quite hard to get to a close enough distance in supercruise to pick up these low amounts. This is why they disappear because they're too low for the scanners to pick up.

The problem I see is that the answer while it may be totally correct is not the same problem that I raise in my issue, since what I raise is that other players' ships disappear and npc in the case that you reduce your speed and they do not do it.

The radar works by detecting the emissions from the ships, is the current operation correct?
If your ship reduces its speed to the minimum, should you just disappear from the radar and be able to continue seeing the ships that enter the system or those who continue to accelerate towards their destination?
Is there a reason for this to happen?
When a ship enters the system in one jump is its thermal footprint reduced in any way?

- I ask this because if you are near the star at minimum speed, you can see how the ship enters the system and automatically disappears from the radar.

Shouldn't the ships thermal footprint always be visible while they are accelerating inside the system?
The npc ships disappear when you slow down your ship, not because their ships slow down.

I know it's a lot to ask, but would it be possible for someone from frontier to explain to us why all this happens on the radar so we can understand it better?

I don't understand how radar works.

Could some developer at a free time review this problem and see that what happens on radar is quite strange and also something that did not work like this before but did it well?

Thank you
 
it is not intuitive...


The intuitive way we thin about this is that the slower you go, the less visible you are, but this would favour a playstyle, where I sit at slow speed, waiting for you to fly by at high speed, and since slow speed = low emissions, you will not see me, but I can see you, so I can now ambush you... and you did not get any warning on your radar, that I another player was in the system (hollow marker on the radar). This would be pretty bad when it comes to player getting ganked by other players.


So instead they made it so that the harder you are to been seen due to slow speed, you have an equally hard time seeing other ships... so you cannot sit mostly still and wait for a suitable ship to pass by and then ambush them, as they have to fly by very close for you to see them.


And as you have noticed, this affects when you move slowly around a star etc. as this is the same mechanics, but atleast around the star we can make some lore reasons to explain this behaviour, your sensors are blinded by the proximity of the star, this also makes it harder for others to locate your ship, as the star masks your signature, even though you burning fuel like crazy, that is still nothing compared to the amount what the star next to you consumes....
 
If you’re talking about Supercruise, the detection range is based on time - how long it would take you to get there.
So if you slow down, it will take you longer and targets go ‘out of range’ and disappear.

Very unintuitive and of course it does not take account of the target speed. They could be out of your range but travelling significantly faster than you are, have you on their radar, and be on you in a few seconds, taking you by surprise.
 
This was indeed changed but longer time ago.

Before you could idle in space and watch all the NPCs and CMDRs. Now your range decreases with speed.
 
When you are below 40 seconds away (based on your speed) from another ship in supercruise you can see them. They may or not be able to see you because the same rule applies to them. It’s in the manual, but with a little less detail.

No sorry the radar doesn't work like that, at 40sl light if you slow down your ship the other ships disappear from your radar, even if they keep their speed and thermal footprint. You can check it

Why do ships disappear from the radar when you slow down your ship? If the system worked by distance, other pilots' ships should not disappear when your ship slows down.

If the system is based on the radiation emitted by the other ships, why do they disappear when your ship's heat emissions drop and the others continue at their normal speed with no change in their thermal signature?

He didn't say 40ls, he said 40 seconds, which is two entirely different things.

Right. And if you are 40 seconds away, then slow down, you will be more than 40 seconds away. When that happens, they disappear from your scanner (not radar) until you get closer that 40 seconds again. Like I said, it’s in the manual, with less detail on page 70.
