question about the ALR56 RWR

[zlm63682]

Hello

have seen an image showing the RWR actually can tell some details of the radar source such as friendly or hostile by putting certain symbols on top of the radar source.

found the F15C RWR can tell a friendly radar source (the E3 in the image)

the F15E doesn't have it, my question is: is it because it's not modelled yet under current development stage or this function does not exist in the real life F15E RWR? I think 15C and 15E use the same type of RWR?

You are mixing different things together.

An RWR does not have the ability to distinguish between friendly or foe. It simply detects a source and classifies that according to the database in the system. Think about, if two countries were at war, with the exact same aircraft, how is it supposed to distinguish between friend or foe if both have the exact same radar?

So, forget about using the F-18 symbology for the RWR of the F-15C. The semi circle above a contact indicates a fresh contact on your RWR.

You are right I just watched some tutorials and the F15C/E doesn't have such capability but the FA18C does have.

oh nooooooo I want this on my F15E

Something about the F-15E RWR that I would like to know, why do all the other US planes seem to use 29 for the MiG-29/Su-27 family, but the F-15E uses SB?

There must be some reason!

SB stands for Slot Back, which is the radar used by the 29. Why they didn't go with 29 I'm not sure, but that's why it's SB at least.

Thanks! Been wondering about that for ages! At least I know the more important part now, of why its actually SB, if not why they decided to be different!

Presumably because its not a 29 you are seeing on the TEWS, its a slotback. Its up to the pilot to determine whether that slotback is mounted in a mig29 or something else. Other airframes are more discrete in their radar usage, and can then be ID'd directly on the TEWS.

Because each RWR database is programmed to how the customer or operator needs it. So two identical RWR units can have different indications for different radars across different countries/operators. The 29 indication in other jets for both the Fulcrum and Flanker is also completely wrong as those two radars are very different and operate on different frequencies. May just be leftovers from FC3 days.

It is left overs and a basic assumption that because it's 'the same radar' (At least  80% of it) that it should appear the same but this should not be the case.
