Possible bugs of the anti-radiation missile

[Sc0tt 3]

I found some major issues of the new ARM.

 

1. It can track ground targets that have NO RADAR. e.g: Target a tank(like T-100) with cannon or IR missile, switch to ARM and shoot, then the missile will try to track the tank(but may not hit precisely everytime).

 

2. It can track target without completing the lock progress. Not sure if it's intented.

 

3. It can perform U-Turn if the acquired target is behind it. This also appears in LOAL mode: Set a radar target somewhere below your plane and dumb fire the ARM to the horizon, then you will see the horrible U-turn after a few seconds.

 

4. In its LOAL mode, the “auto seek” stage is way too late and too close from the target, which cause it always hasn't enough time to turn towards the target and may miss the shot. e.g: Dumb fire the ARM at 3km away from the target(aim at it), the missile will fly straightly until it reaches the range of less than 150m, followed by a sharp turn.

 

5. This is an issue of all kinds of missiles with LOAL(Maddog) ability: When a dumb fired missile starts to auto seek target(steer), it sometimes cause lags or massive FPS drop.

 

Here's some other questions. When an ARM is homing in on a target:

1. If the target turns its radar off, will the missile try to hit its last position or just lose control?

 

2. If the target turns on radar again, will the missile keep track it?

Nice! Thank you!

We are aware of it. This is a behavior of autoSeekTarget (lock-on after launch). If you have a marked target (no matter what vehicle sensor acquired it) the munition with autoSeek will automatically fly towards the target's position. It's not actively tracking the target, it's just flying towards the position. And then in lockSeekRadius the missile will try to acquire a target with the missile's own sensors. If there's no such target available the missile will still fly to the initially marked position. I.e. if the initially marked target moved, the missile won't be able to follow it, unless the target can actually be tracked by missile's own sensors.
It's partially a desired behavior, although not ideal from gameplay pov. The only other option atm would be to remove LOAL capability from HARM missiles.

Similarly to the point above, there's no way atm how to limit missiles with autoSeek in their initial or "fly to a position" phase.

Do you have a video, please, or exact steps? So we're testing the same thing :) (e.g. what missile, how many units in front of the missile, distances...).

It should fly towards the last known/estimated position.

If the target is still within missile lock cone it should.

Thanks a lot again for all the notes!

If you fire a LOAL capable missile towards the horizon without a hardlock or even a data link target detected, will the missile still be able to acquire a target automatically once a valid target (e.g. radar for HARM, aircraft for ARH) appears within the missiles own sensor range?

 

Or does LOAL only work if your aircraft knows about the target thanks to the aircraft's own sensors or a datalink friendly sensing the target?

 

EDIT: I think the above post may have answered this question but it would be nice to get a direct confirmation anyway.

Thanks for the reply.

In LOAL mode the target's position isn't marked, but the missile can make U-Turn too(if close enough to the target). So I think there's also something wrong in the seeking phase: its own sensor(front hemisphere) can detect targets behind it.

The loalDistance parameter should control this.

This is most likely to happen during the first several shots in a scenario. Almost all kinds of missiles with LOAL ability may cause this issue, like ARM, R77 and new SAM. I tested with about 5 units per time.

Of course it will, this is what LOAL is supposed to be.

The vehicle sensors should only provide a initial position for the ARM to fly toward if you select a target with it, then the missile will depend on its own sensor(same to above) which knows no friendly or datalinked unit.

@oukej You'd better check the SDB. It has quite similar (improper)behavior to the ARM. I believe this is also owing to the LOAL feature in current state: munitions always fly to the position marked by vehicle sensors. But why the ARH(AMRAAM, R77...) and LGB are still normal? They should have their autoSeek setted to 1.

 

1. It can lock on and hit COOLED-DOWN radar targets, just use the key “R” to cycle between them.

 

2. It can always hit the target without a solid lock(playing sound).

 

3. Its maneuverability is so “good” that it can fly backward to targets behind it(like the U-Turn of ARM).

This picture illustrates all these issues.

This is probably a good idea. Personally never liked HARM having LOAL anyway, to be honest.
