Question about TWS and RWS

[caponi]

Hi guys,

 

i have a little question.

Look at my first picture with radar mode RWS and you can see 4 contacts in front of me.
the second picture was 2 seconds later with TWS manually and you can see only 2 contacts.

is this the right behaviour ?
ok, i know there are 4 contacts but if i use TWS to fight against 4 fighters i have to ignore two contacts ?

Radars have a concept call range resolution, which is how well the algorithms that run the radar can break out individual targets at a given range. The AWG-9 is a rather old radar, so it doesn't have particularly great range resolution, and will struggle to break out targets that are close together at long ranges.

 

In very oversimplified terms what your radar is actually seeing is a blob where each of the twoships are. RWS as a radar mode doesn't do much processing, where it gets a radar contact it creates a blip at the proper range and azimuth. As it sweeps over the blob it creates a brick wherever it makes contact. It might generate one brick as it sweeps over, it might generate two bricks, so on and so forth. TWS is a mode that does a lot more processing, it's trying to to take multiple radar hits, and fit them into a pattern that will allow it to determine their velocity and vector, but this also means the radar is making guesses. Because each two ship is close together, flying at a similar altitude, direction and speed, TWS makes the assumption they are two small objects but one big object. As the two tracks get closer, or when the two aircraft break formation, the AWG-9 will eventually be able to see them well enough to determine they are in fact individual objects.

Okay, Thank you for the explanation.

Good to know ... !!

Both, for the RIO in the F14 and good for the pilots in the Mig-29

You can mark it as multiple targets on CAP, so you will not forget

Good to know, thx

 

The RIO job is a complex challenge
